Shop introduction: Most of the ancient streets are composed of various shops. There are nearly a hundred existing shops. Except for a few serving local residents, most of them have the functions of wholesale, trade, transshipment, and storage. In the old days, there were 28 kinds of shops in 4 categories, covering most of the commodities in people's lives. Groceries, rice, salt, wood, sugar, tobacco, fruit, meat, and tea were the eight most popular commodities; they were known as the four major Huizhou merchants. The salt, pawn, tea, and wood industries all have a place in the commercial street.
