Introduction to the Health Hall: The Health Hall is one of the main buildings of Guiyun Village. The surrounding hillsides are lined with green trees and the breeze is gentle, making it a perfect place for self-cultivation. Therefore, it was favored by Lu Chengfeng, and he lived here for a long time, and named it "Yangshengtang". Huang Yaoshi once taught Lu Chengfeng about pharmacology here.
