Introduction to the eaves of Shinan Street: Tangqi is a standard water town, with rivers everywhere. The streets in the town are all built along the river and built inside the eaves, commonly known as "street buildings." This Langyan Street is so wide and prosperous that it can be said that there is no other shop in the Jiangnan water town, and it is famous throughout Jiangnan. There is a saying that goes: "After running through three passes and six piers, it is not as good as the eaves of the pond." No wonder, even a postscript in Mr. Feng Zikai’s hometown of Shimen, Tongxiang, is based on Langyan Street in Tangqi, which is called “The rain falls on Tangqi Street - the wheel (drench) cannot catch it”.
