Introduction to the Xizi Furnace: At the head of the village, there is a complete "Xizi Furnace" built in 1886 (the twelfth year of Guangxu). The furnace is a tower-type building with three floors and hexagonal openings. According to local elders, Langshan Village has produced literati in the past dynasties, and there are many people who are good at writing and ink. They often burn unsatisfactory manuscripts in the pagoda and never throw them away, which has developed a good custom of cherishing words. This Xizi furnace is a good example of the Yao people's advocating culture and attaching great importance to education.
