Introduction to the old street: The old street is built next to the stream. It is long and winding. Dozens of independent but closely connected small buildings are strung together into a small street that is nearly a kilometer long. The roof of each building is designed with a beacon wall in the style of Jiangnan residential buildings. The walls are lined up in rows and are well-proportioned. There are three arch bridges and a covered bridge over the stream, which are quite fresh in style.
