Introduction to Gaoyangtai: Gaoyangtai is the residence of Li Gaiwu. This place was originally called "Grape Man". The last patriarch, Li Gaiwu, built a residence here because his brothers separated. He thought the place name was slang and changed the name to "Gaoshan Yangzhi". The mansion covers an area of more than 2,000 square meters and has more than 40 houses. The wide courtyard, the tall main hall, the spectacular embroidered tower, the neat side halls, the scattered side rooms, and the exquisite and intricate wood core stone carvings are breathtaking and lingering.
