White jade is the hall, which refers to the noble place where the mind lives. In ancient times, the main house was often called the hall, which was usually located on the central axis of the residential building complex and was generally occupied by the elderly. This point corresponds to the heart and is located above Zhongting (CV16), hence its name. Song Yu's Feng Fu: "Walking around Zhongting (CV16), heading north to Yutang (CV18)."
