At the south end of the ancient town, there is a heritage complex that used to be the site of Wangsheng Rice Mill – the largest of its kind in southeastern China. The business was owned by two native families – the Shen and Fan families – in the early 20th century. The huge complex contained a rice shop in the front and a mill in the back. The hundred granaries enabled the company to store enormous amounts of rice, and it served as the grain collecting and distributing center for a dozen townships in the area.
