After Yuan Tiangang took the order, he searched all over the banks of the Yellow River, but he didn't find a favorite place. Later, I came to Guanzhong and came out to see the astronomical phenomena in the middle of the night. I saw a purple sky on a mountain, which happened to intersect with Beidou. Yuan Tiangang thought it was a treasure, so he hurried up the mountain to find a suitable place. He couldn't find anything to mark at the moment, so he took out a copper coin and put it on the ground, covered it with aggradation, and then went down the mountain to report to me. Li, another feng shui master, accepted the order and went east along the Weishui River to find the treasure. One day at noon, when the sun was shining, he saw a strange stone mountain protruding from Qinchuan. From south to north, it looks like a young woman sleeping naked under the blue sky and white clouds. This young woman has complete facial features, a pair of strong and symmetrical breasts, even nipples and navel. What surprised him even more was that the young woman's legs were slightly apart, and there was a clear spring flowing in the middle all day! Li Dawei was surprised, and hurried up the mountain. Taking meridian as the picture, he put the gossip on the gravel, pulled out his hair pin and plunged it into the soil where the two fish met, and reported back down the mountain to me. Wu Zetian heard two people say that Ji Di chose the same direction and sent someone to review it. When the minister came to Liangshan, he found Li's hairpin stuck in the money eye of Yuan Tiangang copper coin! Wu Zetian ordered the immediate construction, and soon Ganling was repaired. Tang Gaozong was buried, and then her husband was buried in Ganling. The terrain of Ganling should be a perfect combination of Yin and Yang and the best coordination between heaven and earth. Dry for the sky is yang, Kun for the earth is yin, and yin and yang make everything happen. In the history of China, there are two dry tombs-Li Zhi in Tang Gaozong and Lu Xian in Liaojing Sect, one in Ganxian County, Shaanxi Province, and the other in Beining, Liaoning Province. The two tombs are separated by 300 years. Interestingly, there are many similarities between the two mausoleums-not only the names of the mausoleums are the same, but also the emperor was unable to go to court because of long-term illness after he acceded to the throne. Empress Wu Zetian and Empress Dowager Xiao became regents, and the emperors all died first. Empresses and concubines have all been empresses, and they have all done things beneficial to the people. They all developed society and became female politicians, and they all had erotic history. After their death, they were all buried in Ganling, which is rare in all tombs of past dynasties.
