< p>Qiantang River is in Hangzhou, Zhejiang.The Qiantang River Bridge in Binjiang District, Hangzhou City, Zhejiang Province, is a free all-day attraction. The origin of the names of most provinces in China has a source of geographical knowledge. The origin of the name Zhejiang Province is the Qiantang River, a river whose drainage basin covers most of Zhejiang Province. It can be said that Qiantang River is the mother river of Zhejiang Province, and the ancient name of Qiantang River is "Zhejiang", which is the name of Zhejiang Province. From this.
Introduction to Qiantang River
Qiantang River, called Zhejiang in ancient times, its full name is "Zhejiang", also known as "Zhejiang", "Zhijiang", "Luochajiang", generally Fuyang, Zhejiang The section in Hangzhou, Zhejiang Province is called the Qiantang River.
The Qiantang River was first named in the Classic of Mountains and Seas. It was named after it flowed through ancient Qiantang County (now Hangzhou) and was one of the main birthplaces of Wuyue culture. Qiantang River is the largest river in Zhejiang Province. It was the source of the name of the two Zhejiang roads in the Song Dynasty and the source of the name of the province when Zhejiang Province was established in the early Ming Dynasty.
Starting from the Xin'an River in the north, the river length is about 588.73 kilometers; starting from the Ma Jinxi River in the upper reaches of the Qujiang River in the south, the river length is about 522.22 kilometers. From its source, it flows through present-day southern Anhui Province and Zhejiang Province, with a basin area of ??approximately 55,058 square kilometers, and flows into the East China Sea through Hangzhou Bay.
The Qiantang River Bridge was built in 1934 and has a history of more than 80 years. In fact, this bridge is not only the first bridge on the Qiantang River, but also the first highway and highway designed and built by my country. The main designer of the double-decker railway bridge is Mao Yisheng, a famous bridge scientist in my country. In what province is the Qiantang River located?
The Qiantang River is located in Hangzhou City, Zhejiang Province. The Qiantang River eventually flows into the East China Sea. The tide at its mouth is the Qiantang Tide. Few tourists come to see this spectacle. Before the arrival of the tide, a tiny white dot first appeared in the distance, and in a blink of an eye it turned into a silver thread on the Qiantang River in Hangzhou. The white thread rolled in accompanied by bursts of thunderous tide sounds.
With almost no time for people to react, the surging tide has roared in. The peak of the tide is 3-5 meters high. The waves behind are catching up with the waves ahead, one layer after another, like a long white belt. It has the potential to overwhelm mountains and seas. The poem says: "As soon as I look at Qiantang, there are endless waves, and suddenly there are violent waves in front of me. The seemingly ordinary river water contains shocking energy."
Historical evolution:
To watch the autumn tide in Qiantang, early in the morning It had become a trend in the Han, Wei and Six Dynasties, and became even more popular in the Tang and Song Dynasties. According to legend, August 18th of the lunar calendar is the birthday of the Tide God, so the tide peak is the highest. The court of the Southern Song Dynasty once stipulated that on this day, the navy would conduct a military parade on the Qiantang River. From then on, it became a custom, and August 18th gradually became a tide watching festival.
The poet Pan Lang of the Northern Song Dynasty wrote in "Jiuquanzi": I remember watching the tide for a long time, and the Manguo people competed to look up the river. The vast sea of ??doubts has become empty, amid the sound of thousands of drums. The tide boy stands facing the waves, holding the red flag in his hand without getting wet. Don't come here and look into the dream, the dream is still chilling. This poem is a true portrayal of the activities of "making the tide" and "watching the tide" back then. Where is the Qiantang River
The Qiantang River is located in Hangzhou City, Zhejiang Province.
Qiantang River, known as Zhejiang in ancient times, its full name is "Zhejiang", also known as "Zhejiang", "Zhijiang" and "Luochajiang". Generally, the Fuyang section of Zhejiang is called Fuchun River, and the downstream Hangzhou section of Zhejiang is called Qiantang River. The Qiantang River was first named in "The Classic of Mountains and Seas" and was named after it flowed through ancient Qiantang County (now Hangzhou). It is one of the main birthplaces of Wuyue culture.
Qiantang River is the largest river in Zhejiang Province. It was the source of the name of the two Zhejiang roads in the Song Dynasty and the source of the name of the province when Zhejiang Province was established in the early Ming Dynasty. Starting from the Xin'an River in the north, the river is 588.73 kilometers long; starting from the Ma Jinxi River in the upper reaches of the Qujiang River in the south, the river is 522.22 kilometers long. From its source, it flows through southern Anhui Province and Zhejiang Province, with a basin area of ??55,058 square kilometers, and flows into the East China Sea through Hangzhou Bay.
The Qiantang River tide is known as the "first tide in the world" and is a natural wonder in the world. It is caused by the centrifugal effect of celestial gravity and the rotation of the earth, as well as the special topography of the bell mouth of Hangzhou Bay. Extraordinary tidal surge.
The best place to watch the spring tide of the Qiantang River
1. The geographical location of the Qiantang Tide: Hangzhou Bay, Zhejiang Province, where the Qiantang River enters the sea. The best places to watch the Qiantang River tide are Jiangnan and Jiangbei in Hangzhou.
2. As long as you arrive in Hangzhou, during the days when there are tidal floods, you may see the tide in any area along the Qiantang River. There are two tides in a day, morning tide and late tide. The next day's tide is generally 40 minutes later than the previous day's tide. Just pay attention to the local forecast when you arrive in Hangzhou.
3. If you want to see the first line of tide, it is best to go to Haining, or at least to the lower reaches of the Sixth Bridge of the Qiantang River. If you want to see the back tide, you can go to Xiaoshan Tide Watching City or along the river in Xiasha area. However, it is more expensive to go to Haining or Xiaoshan to watch the tide. From the local people's point of view, there is no need to spend that money.
4. Introduce a few places on the edge of Hangzhou and on the upper reaches of the Qiantang River where you can see the more spectacular tides without spending any money:
Jiangbei: A. See Tide back to the coral sand. (It is more than a thousand meters west of the Liuhe Pagoda, so the Qiantang River Bridge-Coral Sand area is OK); B. Watch the first line of tide to the Qiantang River Xixing Bridge. (Downstream - Xiasha area); if you go to the other side of the Yangtze River, you can also go.
Jiangnan: There is a place called Banpetan Mountain between Puyan and Wenyan. It is the best place to watch the tide in the upper reaches. Take bus 522 or 322 and get off at Longshan Chemical Plant Station, then walk more than a thousand meters west to the riverside. (Watching the tide should be a little downstream of Banpetan Mountain, where the Qiantang River tide turns through the coral sand to form the last climax)
5. It is recommended to watch the early tide in Jiangbei and go to Banpetan Mountain to watch the late tide. . You have to get up at midnight to see the morning tide, and leave before 14:00 to see the evening tide.
For the above information, refer to Baidu Encyclopedia Qiantang River. In which province and city is the Qiantang River located?
The Qiantang River is located in Hangzhou City, Zhejiang Province. It is a section of the river from the Qiantang River to the mouth of the sea. The upper reaches of the Qiantang River are no longer called the Qiantang River. The section out of Anhui is called the Xin'an River. The section that flows through Tonglu and meets the Fuchun River Reservoir is called the Fuchun River.
Qiantang River is the largest river in Zhejiang Province and the source of the name of the province when Zhejiang Province was established in the early Ming Dynasty. The tidal wave of the Qiantang River is very spectacular and is known as the best tidal wave in the world. It is a natural wonder in the world. Qianjiang Qiutao is famous at home and abroad, and many people come to visit it every tide watching day. The reason for this phenomenon is due to the centrifugal effect of celestial gravity and the earth's rotation, coupled with the special topography of the bell mouth of Hangzhou Bay.

Analysis:
< p> ■Qiantang RiverThe largest river in Zhejiang Province. In ancient times, it was called Zhejiang, Zhejiang River, Zhejiang River, and Zhihe River. It originates from the east slope of Liugujian in the Huaiyu Mountains in the southwest of Xiuning County, Anhui Province, at the junction of Anhui and Jiangxi provinces (Liugujian is 1,629.8 meters above sea level, and the source is about 1,350 meters above sea level). The main stream flows through Anhui and Zhejiang provinces, and enters Hangzhou Bay from the southeastern mouth of Chanpu Changshan in Haiyan County to the West Third Gate on the border of Yuyao City and Cixi County. It has a total length of 605 kilometers and a drainage area of ??more than 48,800 square kilometers. It is between 28°04′～30°24′ north latitude and 117°39′～121°14′ east longitude. The terrain of the basin slopes from southwest to northeast, and the main stream flows northeast into Hangzhou Bay. The river is a plume-shaped water system.
Overview of the main stream The main stream is upstream above the Xin'anjiang Hydropower Station. The upper source Fengcun River flows through the mountains of southern Anhui to Hecheng, Xiuning County, where it joins the source of Meixi River originating from Wugujian of Huaiyu Mountain, and is called Dayuan River. The tributaries collected along the Dayuan River have short sources and rapid flows. It is called Shuishui from Liukou Hexiaoyuan River in Xiuning County to Tunxi City. When it reaches the Hengjiang River, a tributary of Tunxi River, it is called Jianjiang River. At Pukou of She County, Lianjiang River flows in from the north. The area from Pukou to Meicheng Town, Jiande County, Zhejiang Province is called Xin'anjiang River. Below the street entrance of Shexian County, it is a mountain stream.
The middle reaches are from Xin'anjiang Hydropower Station to Fuchunjiang Hydropower Station. The Xin'an River flows to Meicheng and receives the tributaries Lanjiang River and Tongjiang River. The three rivers converge into a "T" shape. The Lanjiang River is the largest tributary of the Qiantang River and one of the main sources of water in the Qiantang River. The upper reaches of the Majin River originate from the northern slope of Qingzhidaijian in the south of Xiuning County, Anhui Province. The distance between the two ports of Quzhou City and Najiangshan Port is called Changshan Port. Changshan Port mostly flows through mountainous areas and is a mountain stream. The area from Quzhou City to Lanxi is called Qujiang (or Qugang, Xin'an River), and the area from Lanxi to Meicheng is called Lanjiang. The Qujiang River flows through the Jinqu Basin. The river channel is wide and the water is deep and slow. When it leaves the Jinqu Basin, the riverbed gradually becomes deeper. Tongjiang River is a tributary from Meicheng to Tonglu. It starts from Wushitan about 7 kilometers below Meicheng and enters the famous Qililong Canyon. The total length of the canyon is about 22 kilometers. After the Fuchun River Hydropower Station was built to store water, the surface of the Qililong River widened and the original shoal was submerged into the water; parts of the Lanjiang and Tongjiang rivers formed reservoirs. After leaving Qililong, the river opens up.
The area below the Fuchun River Hydropower Station is the downstream. Affected by the tide, it belongs to the Qiantang River estuary area. From Tonglu to Wenyan in Xiaoshan County, it is called the Fuchun River. The river bed is open and stable, the water flow is slow, the accumulation is significant, and the floodplain is developed, and it is basically not affected by sand from the sea. From Wenyan to Hangzhou Zhakou, the river bed is wide and shallow and the river channel is winding and winding, shaped like the character "Zhi", so it is also called Zhijiang. The area below the gate was first called the Qiantang River, and later generally referred to the entire river, which is characterized by surging tides. Below Kanpu is Hangzhou Bay. The main tributaries of the lower section include Huyuan River, Puyang River and Cao'e River on the right bank; Fenshui River and Luzhu River on the left bank.
Climate and Hydrology The Qiantang River Basin has a mid-subtropical monsoon climate. The annual precipitation is 1,600 to 2,000 mm, and the precipitation in the mountains in the upper reaches of the main stream is higher than that in the hills and plains in the middle and lower reaches. Runoff recharge is dominated by rainwater, with only a small amount of groundwater. The total runoff volume of the Qiantang River reaches 43.1 billion cubic meters, and the runoff depth is 880 mm.
The seasonal distribution of runoff in the Qiantang River is uneven, with huge differences in flood and dry flow. In most areas (the main stream is above Fuyang), precipitation is the highest between May and June, and the maximum runoff of rivers occurs during this period. The runoff from May to June at Quxian Station accounts for 42.2% of the annual total; and at Lucibu Station it accounts for 39.3%. The inter-annual variation of runoff is small, the annual runoff variation coefficient is 0.28-0.38, and the inter-annual extreme value ratio is also small. The water erosion modulus of the Qiantang River Basin is 100 to 500 tons/square kilometer/year. The high values ??are in the Cao'e River and Puyang River basins, and the low values ??are above Changshan Mountain. The average sediment content of the Qiantang River is 0.1 to 0.4 kg/cubic meter. The average annual sand transport volume is 6.68 million tons. The river water is clear all year round, but becomes turbid during flood periods. River water has low salinity, hardness and alkalinity.
Qiantang Tide The Qiantang River Tide is one of the world's famous spring tides. Especially the 18th day of the eighth lunar month is the most spectacular. The formation of tidal waves is closely related to topography. Hangzhou Bay is a typical trumpet-shaped estuary. Its width shrinks sharply from the mouth of the bay inward. It is 100 kilometers wide from the mouth of the bay, 20 kilometers wide to the water surface of Kanpu, and only 1 kilometer wide to Hangzhou. As the tide goes back, the water body is severely constrained, the tidal wave energy is highly concentrated, and the tidal range increases significantly. The tidal range in Kanpu is twice as large as that at the bay mouth. The average tidal range is about 5 meters, and the maximum tidal range occurs in Kanpu, reaching 8.93 meters. At the same time, the longitudinal profile of the Qiantang River estuary has unique characteristics. The riverbed in Hangzhou Bay is flat and begins to rise from above Zhapu. The highest point of the rise is between Qibao and Cangqian, and the highest point is about 10 meters above the baseline. It is 130 kilometers long from Wenyan to Zhapu and is a huge sand ridge uplift. The huge sand sill quickly raises the riverbed above Kanpu, and the water depth at low tide becomes shallower from the mouth of the bay inward. The average water depth is 2 to 3 meters, sometimes only about 1 meter. During the propagation process of the tidal wave, because the river bottom gradually becomes shallower, the propagation speed of the tidal peak is much greater than that of the tidal valley. The front slope of the tidal wave gradually becomes steeper, and the back wave continues to slow down. The deformation of the tidal wave intensifies, and a tidal surge is formed near Jianshan. The tidal surge is the largest near Haining City, with a general height of 1 to 2 meters, and a maximum height of 3.7 meters. The tidal surge gradually weakens near Hangzhou.
When the Qiantang River is turbulent, seawater flows back, carrying a large amount of sediment mainly from the Yangtze River, which is transported by seawater and deposited in the river mouth, becoming the main source of sandbank sediment. At the same time, the river bed is raised and the water depth becomes shallower, which seriously affects the shipping and aquaculture fishing and aquaculture benefits of the river mouth. In order to prevent tides, a seawall project as famous as the Great Wall and the Beijing-Hangzhou Canal was built in Kulai, and it has been continuously reinforced in the past dynasties and since 1949.
Cascade development and comprehensive utilization The entire basin is rich in hydropower resources, with a developable energy of approximately 2.05 million kilowatts. By the end of 1978, the developed installed capacity was 1.319 million kilowatts. Tidal energy is greater in estuary areas. Since the 1950s, cascade development has been carried out on the Qiantang River. Reservoirs and hydropower stations such as the Xin'an River, Fuchun River, Huangtankou and Hunan Town have been built. The Xin'an River Hydropower Station has a total storage capacity of 22 billion cubic meters and an installed capacity of more than 650,000 kilowatts; the Fuchun River Hydropower Station has a total storage capacity of 874 million cubic meters and an installed capacity of 297,200 cubic meters. kilowatt. The Huangtankou and Hunan Town hydropower stations were built as a two-stage cascade development of the tributary Wuxi River.
The main channel below Lanxi in Qiantang River is navigable for ships of 30 to 100 tons. Only offshore ferries are available below Hangzhou. Xin'an River is an important waterway connecting western Zhejiang and southern Anhui. The waterway is interrupted at the Xin'an River Dam, and the upper and lower sections are navigable. Steamers can go up to Tunxi, Anhui Province upstream of Xin'an River. Other tributaries and reservoirs also have navigable miles at varying distances. The basin is densely populated and economically developed. The valleys on both sides of the river are good farming areas. The mountains are rich in wood and bamboo. The tidal flats in the estuary area are vast.
At the end of 1988, a 7-kilometer-long river channel was excavated through the northeast corner of Hangzhou City to reconnect the Qiantang River and the Beijing-Hangzhou Canal, realizing the connection between the Beijing-Hangzhou Canal and the five major water systems of the Yangtze River, Yellow River, Huaihe River, Haihe River, and Qiantang River. Connect and expand the direct water transportation distance to 400 kilometers, forming a water transportation network centered on Hangzhou.
Qiantang River’s natural scenery and man-made buildings are intertwined. Tracing the Qiantang River and crossing the Fuchun River to the Xin'an River, it forms a tourist attraction and has been listed as one of the first batch of key scenic spots in China.
■Qiantang Estuary
Strong tidal estuary. The river mouth area stretches from Lucibu, the boundary of the Chaozhou District, to the mouth of Hangzhou Bay, with a total length of 274 kilometers. It can be divided into three sections: from Lucibu to Wenjiayan, 83 kilometers long, controlled by runoff, with many central river islands in the river, and the river bed is relatively stable, so it is a near-mouth section; from Wenjiayan to Kanpu, 101 kilometers long, controlled by runoff and tidal currents Interaction, surging tides, and changeable riverbed; it belongs to the estuary section; the area below Kanpu is commonly called Hangzhou Bay, 90 kilometers long, with weak influence of runoff, and is trumpet-shaped. It is 100 kilometers wide from Nanhuizui at the mouth of the bay to the mouth of Yongjiang River, with Kanpu at the top of the bay. The section is 20 kilometers wide and is the seaside outside the mouth. There are many islands outside the mouth of the bay, called Zhoushan Islands.
In the early years of the Eastern Han Dynasty, Wang Chong was the first to discuss the astronomical and topographical conditions for the formation of the Qiantang River surge. In order to resist the invasion of tidal waves, seawall projects have been built on a large scale since the Tang Dynasty. Since the 1950s, systematic investigations and studies have been conducted on the hydrology, sedimentation, and river channel evolution of the estuary area. The large-scale reclamation project started in the late 1960s had a significant impact on the evolution of the tidal river section.
About 6,000 years ago, during the post-glacial period, the Qiantang River estuary became a submerged valley due to sea intrusion. Afterwards, the sea level dropped and sedimentation continued. The north bank was the southern wing of the Yangtze River Delta, and the coastline was from Jinshan to Wangpanshan to Han. Pu first line. In the past 2000 years, Hangzhou Bay has swollen in the south and collapsed in the north, with drastic changes. The south bank extends from Shaoxing, Shangyu, and Hushan, while large areas of land outside Zhapu and Jinshan have collapsed, and Wangpanshan has fallen into the bay. Because the power of the tide is much greater than that of the river, the sediment is carried into the giant sand sill between Zhapu and Wenjiayan and accumulates for 130 kilometers. The top of the beach is 10 meters above the baseline, and the volume reaches 42.5 billion cubic meters. The main material is uniform silt.
The runoff of the Qiantang River has a large amplitude and carries little sand. The seasonal changes of incoming water and sediment are large. The water volume from March to June accounts for 57% of the whole year, and the water volume from October to January of the following year is only 15.6% of the whole year. The multi-year average flow is 1468 meters (/second), Lucibu Station The measured maximum flow rate is 29,000 meters/second (June 1955), and the minimum flow rate is 27 meters/second. The total annual runoff in the entire basin is 46.3 billion cubic meters. The annual average sediment content is 0.2 kg/m, and the annual sediment load is 7.03 million tons.
Since the width of Hangzhou Bay shrinks sharply from the outside to the inside, the average tidal range in Zhenhai on the south bank of the bay is 1.69 meters, and the average tidal range in Kanpu at the top of the bay is 5.45 meters. , the maximum tidal range is 8.93 meters. The average flow in and out of the Kanpu section is 140,000 meters/second, which is much larger than the water in the basin. The tidal range on the north bank is larger than that on the south bank. Luchao Port is 1.49 meters larger than Zhenhai, west of Kanpu. The river bed narrows and rises sharply, and the tidal wave deforms violently, resulting in the world-famous Qianjiang tidal wave near Jianshan. The tidal wave is the highest in the Yanguan area (formerly known as Haining). The tidal head is usually 1 to 2 meters, and the actual measured maximum is 3 meters. The propagation speed of tidal waves is 8 to 10 meters/second. The tidal surge is very destructive. It has been measured that the tidal surge pressure reaches 7 tons/meter, and concrete blocks weighing 25 tons at the head of the dike are sometimes washed away. The maximum vertical flow velocity in the Yanguan area is as high as 4 to 5 meters per second. In the river section above Yanguan, the velocity of the rising tide is about twice that of the falling tide. The amount of sediment carried by the tide changes with the flow speed in Jianshan and Yanguan. The sand content in this area is the largest, with the measured maximum sand content being as high as 51 kg/m. The average sand content in Kanpu is generally 3-4 kg/m, and the average amount of sand flowing in and out per tide is about 10 million tons.
< p> The dilute water of the Yangtze River has a significant impact on the distribution of salinity in the water body of Hangzhou Bay. The horizontal distribution of salinity is higher in the south and lower in the north. Due to the strong tidal current, the salt and fresh water mixture in the Qiantang River estuary is vertically uniform. The salt water intrusion boundary moves up and down with the runoff of the Qiantang River. The salt water in the dry season can be traced up to Hangzhou City, affecting the industrial, agricultural and domestic water use in Hangzhou City.The river bed in the mouth section is wide and shallow, and the water depth at low tide is 1. ~3 meters, the intertidal zone is very broad. Under the influence of strong and divergent flow paths, the riverbed deforms violently as the relative strength of runoff and tidal current increases.
In the autumn when the runoff is weak and the tide is strong, the main trough swings in the direction of the rising tide. In the season of heavy runoff, the main trough swings in the direction of the main flow of the ebb tide. With the alternation of wet and dry years, the main trough swing also changes over the years. For example, from 1962 to 1969, the main trough near Jianshan oscillated nearly 20 kilometers. During the swing of the main trough, the beach on the side hit by the mainstream collapsed and retreated rapidly. A record of 245 meters of high beach collapse in one day was measured. The vertical erosion and siltation changes of the river bed are also very strong. The river section above Yanguan is eroded during the flood season and silted up during the dry season, while the opposite is true for the lower river sections. The average erosion and siltation amplitude of the river bed can reach 5 meters.
Since the 1960s, 900,000 acres of tidal flats have been reclaimed, narrowing three-quarters of the more than 60 kilometers of river channels above Babao in Haining County. There are excellent natural deep-water port sites on both sides of the Jintang Waterway on the south coast of Hangzhou Bay, and the 100,000-ton Beilun Port Terminal has been built. The Shanghai petrochemical base has been built on the north bank. Rivers such as the Yangtze River and Qiantang River continuously supply abundant nutrients and salts, making the sea area south of the bay mouth the largest fishing ground in my country.
■Qiantang River Tide
A phenomenon in which the tide surges at the mouth of the Qiantang River in Hangzhou Bay, China. It looks like a vertical wall of water, rolling in. The tidal range at the mouth of the Qiantang River is very large. The estuary is wide and funnel-shaped and the river bed is flat. As a result, when the tidal waves from the Pacific Ocean spread to this area, the tidal range increases dramatically. The tidal wave entering Hangzhou Bay meets the river at the mouth of the Qiantang River. The wave surface encounters great resistance, and the front edge of the wave crest breaks. It also encounters an underwater sand bar, causing the tidal wave to divide into two branches, the East Lake and the South Lake, and continue to advance towards the estuary. Between Jianshan and Haining, water columns can sometimes rise more than 10 meters high. The broken tidal peak appears as rolling white waves, 1 to 2 meters high, spreading at a speed of 4 to 6 meters per second, and the tide level rises to more than 2 meters in a short period of time. Every year, as the autumnal equinox approaches, it coincides with spring tides and the rainy season. The average sea level rises. The tidal range in Haining can be as high as 9 meters, and the phenomenon of tidal surges is extremely prominent. If there is a strong easterly or southeasterly wind, the tidal scene will be even more spectacular.
■Qiantang River Bridge
The first double-layer truss girder bridge built by China itself for both highway and railway purposes. Located in Hangzhou City, Zhejiang Province. Built in 1937. It was built by Mao Yisheng and Luo Ying. The total length is 1,453 meters, and the main bridge is 1,072 meters long. It is composed of 16 simply supported riveted steel truss beams with a span of 65.84 meters. The south approach bridge is 381 meters long and is composed of a double-hinged steel truss arch bridge and a reinforced concrete rigid frame bridge. Due to the quicksand at the bottom of the river up to 40 meters deep and the tide of the Qiantang River, the bridge construction project was very arduous. Three months after the bridge was built, before the Japanese army invaded Hangzhou, China blew it up and rebuilt it after the victory of the Anti-Japanese War.
