Who can tell me the history of Yangcheng Lake and Puppet Lake in Kunshan City? How long have they been formed? Ask god for help

There are five lakes in bacheng town, the most famous of which is Yangcheng Lake, which is famous for its rich crabs, followed by Muppet Lake, Eel Lake, Bacheng Lake and Luocheng Lake, all of which are her twin sisters geographically and geomorphologically. Puppet Lake, located between Zhengyi Town and bacheng town, adjacent to Yangcheng Lake, is currently listed as a first-class water resource lake in Kunshan City, where most of the city's tap water comes from. Speaking of this strange lake name, not many people know its origin. Actually, she has two names. People on the west coast call it Puppet Lake, and people on the east coast call it Li Mao Lake. The word "puppet" is named after ghost play, while "hat" is called to ward off evil spirits. Puppet Lake, like Yangcheng Lake, was originally a city and a small town, which was buried in an earthquake in the middle of Ming Dynasty. In the past, when farmers dug mud in the lake, they often found ancient gravel tanks. People often go to the bottom of the lake to dig buried black mud made of trees to make mud cakes instead of coal cakes. You can clearly see the slate street at the bottom of the lake in many places. Yangcheng Lake was originally called "Yangcheng Lake", but now the tail of that city is still there. Her name is Ba Cheng. On the west bank of Puppet Lake, next to Yangcheng Lake, there is a large flat-topped mound across a ridge, with a height of more than 15 meters and a circumference of more than 1000 meters. According to legend, Emperor Xuanzong of the Tang Dynasty was buried at this time, and Huang Zanchuo was named Chuodun Mountain. Huang Zanzhuo is good at performing the drama of joining the army, and often performs on the same stage with the poet Zhang Hui, which once caused a sensation in the Imperial Capital. In his later years, Huang lived in the south of the Yangtze River, living in and out of the rich and powerful families, and left many beautiful songs for the gentry in this area. At that time, it was so popular that it was called "Zheng Sheng" everywhere. It is said that it was later cut into a water mill cavity for Kunqu opera. For hundreds of years, whenever the spring breeze turns green in Jiang Nanan, folk troupes have to perform on Chuodun Mountain to commemorate it. During the Song and Yuan Dynasties, puppet shows prevailed in this area, so the word "puppet" was used as the name of the lake. Let's talk about how Li Maohu got his name: a puppet show is a ghost show. In ancient times, due to inconvenient transportation, there was little cross-strait communication, people on the east coast were often robbed by lake thieves, and some sporadic small villages along the lake gradually declined. So, in order to ward off evil spirits, a stone statue with a big hat was set up on the east bank of the lake, facing Chuodun Mountain from a distance, guarding the people. Therefore, people on the east coast call it Li Mao Lake. (Xu Xiaodong)
