Introduction to Wanyitang: Wanyitang was built in the twelfth year of Tongzhi (1873) after the death of Zeng Guofan. It is a relatively large-scale residence with Ming Dynasty style presided over by Zeng Guohuang. Its name means "eternal generations" and "Easy room IKEA". Nowadays, apart from the demolition of the surrounding walls, trough gates and east and west pavilions, the main building of Wanyitang is intact, and the carvings and paintings on the walls are still clearly visible.
