Introduction to old streets: The existing old street blocks cover an area of about 6 hectares, with a total street length of 1,500 meters and a width of 4 meters; Shangjie Street, Xiajie Street, Zhengjie, Hengjie, Pawnshop Street, Wangzi Street, Shenjie Street Home lanes crisscross each other, forming a chain of markets. The streets are paved with stone slabs and are full of ruts and stone nests. You can imagine the scene of "cars like flowing water and horses like dragons" back then. On both sides are old houses in the Huizhou style, with blue bricks and black tiles, wooden eaves and heavy pavilions, and horse-head walls. They smell like old wine. Visitors walking into it feel like walking through a lane leading to history. The deeper they go, the stronger the sense of oppression of the vicissitudes of time becomes.
