The cleaner found a piece of scrap iron and sold it to an antique shop at the price of 20 yuan. Now it is listed as a national treasure, and it is forbidden to exhibit.

Thousands of years of ancient civilization history in China has created splendid civilization and cultural achievements, leaving precious spirit and wealth for future generations. These precious cultural relics have experienced thousands of years of vicissitudes, some were destroyed by war, some were lost overseas, and some were discovered unintentionally. For example, the cleaning lady found a piece of scrap iron while cleaning the street, and the last 20 yuan was sold to an antique shop. Now it has become a national treasure cultural relic for everyone to visit.

In May, 2006, Aunt Jiang, who was in charge of the garbage cleaning of river banks in Dongyang City, Jinhua City, Zhejiang Province, picked up waste paper and garbage on river banks and rivers as usual. Today, there is a lot of rubbish. While cleaning up, Aunt Jiang scolded pedestrians for littering. Although Aunt Jiang works very hard, at work, she can often pick up some scrap iron and copper in exchange for some money to subsidize her family.

Aunt Jiang may have something to do today and wants to go home early, so her work speed is much faster. Inadvertently, Aunt Jiang tripped over an unknown object and her head was bleeding. Angry aunt Jiang got up and kicked two feet at this stumbling block, only to find that her toe was broken. Her first reaction was to pick up the hard object and throw it away. To her surprise, the stumbling block turned out to be a big iron block, which made her rich!

Aunt Jiang was only happy for a while when she found the problem. The middle of the big iron block is empty, and the river is full of mud and heavy, so she can't move it at all. In desperation, the aunt picked up the hammer she carried with her, smashed it three times, then picked up the pieces and put them in the woven bag prepared in advance, and went home happily. Two days later, a waste collector passed by Aunt Jiang downstairs, and Aunt hurried downstairs to sell the scrap iron she had picked up. The rag collector looked at the scrap iron carefully and said to his aunt, "Where is this iron? It is obviously a copper block with some exquisite words and patterns on it. It may be an antique! " ! You'd better go to the antique shop to have an appraisal.

Aunt was ecstatic and carried the Dongyang antique shop on her back. The owner of the antique shop was stunned at a glance. This is bronze, something from the Western Zhou Dynasty. So the owner of the antique shop immediately contacted the cultural relics department of Dongyang City and gave the aunt 20 yuan, saying that she had accepted it. Aunt Jiang knew it was a treasure, so she said she didn't want to sell it and was about to leave. The owner of the antique shop reminded her: "This is a cultural relic, but if you damage it, you will go to jail." Hearing this, Aunt Jiang picked up 20 yuan's money and went home.

When the people from Dongyang Cultural Management Office came and stared at a piece of land for a long time, my heart was broken. The number of cultural relics supervisors is exactly 16. According to archaeological experts, this bronze bell belongs to the musical instrument "Yongzhong" in the Spring and Autumn Period. After that, under the arrangement of cultural relics experts, the most powerful force was immediately organized to repair the cultural relics. However, the repair took a month, and the repair mainly used lost wax casting, which was unprecedented in technical difficulty.

Today, this clock is preserved in the Zhejiang Provincial Museum and is a treasure of the town hall. It is very precious. Due to the difficulty of restoration and the high value of the national treasure itself, the state prohibits some exhibitions.
