It has 34 rooms on each floor, totaling 136 rooms. It was built by the Jian family and is one of the World Heritage sites of “Fujian Tulou.”

　　    Huaiyuan Building is a two-ring structure. Its architect was the same person who designed the Zhencheng Building, and the design of the building is quite symmetrical.
