Laoshan Taiqing Palace is located in the east, which is the essence of Laoshan Feng Shui. It is well known that Feng Shui is good (there are jade veins underground). The daily drinking water of Taoist priests in Taiqing Palace comes from Yujing behind Sanqing Hall. It is called Yujing because when a well was drilled many years ago, there was high-quality Laoshan jade on the well rope, which means that the well was drilled on jade, and all the water contained many high-quality ingredients of jade. In ancient times, jade was used for beauty and health preservation. Taoist priests drank it every day, which was natural and healthy and lived forever.
