Why is Shizhuang Town in Rugao poor?

In the history of Shizhuang Town, there was a catastrophe. Because of the collapse on both sides of the Yangtze River, the Millennium ancient town was taken away by the vast rivers. Now shi zhuang zhen is a reconstruction town 20 kilometers north of the original site. Nowadays, the only old building that has been basically preserved in this town is North Street, which has a very profound historical and cultural heritage. What you see in the street are all the things you remember when you were a child, such as small noodle shops, biscuit stalls, antique collection shops and so on. It is full of childhood memories.
