Introduction to Lang Defeng Ancient House: Lang Defeng Ancient House was built during the Guangxu period of the Qing Dynasty by Lang Gongzi Heng, the ninth generation descendant of the Lang family. The main gate faces south, with the inscription "Wan Fu You Tong" on the forehead. The architectural model is a hard hill with two slopes, two floors, and a bucket-through style. The Lang's old house has a history of more than 300 years and is one of the oldest houses in the ancient city. Tourists can live in a 300-year-old house here, look at the quaint stone window grilles and wooden window grilles, sleep on carved beds, step on bluestone slabs, and eat authentic farm food. They can also find scenes from the TV series "Sea of the Sea" here. The prototype of Anu's mother's home in "The Gate".
