Introduction to Yongmutang: Yongmutang was originally located in Diwei Village, Hu Town, Longyou County, with a construction area of 540 square meters. It is the ancestral hall of the Xu clan and is called "the hall" by the locals. The words "Built in the 12th year of Jiaqing" are written on the central spine of the building. According to research, in the early Qing Dynasty, the Xu family moved from Hengshan to Houxu and set up the main ancestral hall in Qidu. Later, it branched from Qidu to Diwei. The building has three entrances and three bays, which are divided into foyer, middle hall and back building. The stage and architecture are famous for their wood carvings.
