Introduction to Dunshan Bookstore: Dunshan Bookstore, located on the top of Fenghuang Gang, is the only private building in Licha Village. The bookstore is a small courtyard. The lintel, door frame, floor and steps are all made of granite. The lintel is engraved with the four regular script characters "Dunshan Bookstore". The main building of the study has three bays, with a square patio in front, a wing on the left and right, and an aisle gatehouse on the right. The main room is very high and wide, about ten meters tall, with a portrait of Confucius enshrined in the middle. The most unique thing is that there are two thick logs hanging in the house, which may mean "pillars". According to reports, Dunshan Bookstore has trained many "Tanhua" and "Jinshi", but due to the lack of corresponding local chronicles and genealogy information, it is impossible to determine. It is hoped that researchers can sort out biographies of characters based on local chronicles for the enjoyment of tourists.
