Is the feng shui of the emperor's sacrifice to heaven good?

In ancient China, soon after the emperor succeeded to the throne, he could start building his own mausoleum, because it was a big project, and the address of the mausoleum had to be selected before the construction began. Ganling, located in Liangshan, 6 kilometers north of Ganxian County, Xianyang City, Shaanxi Province, is the burial tomb of Tang Gaozong Li Zhi and Wu Zetian, covering an area of 40 square kilometers.

The ancients regarded death as life, and the emperor would choose a feng shui treasure house as his tomb in advance. In 706 AD, a generation of empress Wu Zetian was buried in Ganling, but to everyone's surprise, after thousands of years of natural and man-made disasters, Wu Zetian's Ganling was never destroyed, let alone stolen. What the hell is this? Is it related to the feng shui of the mausoleum?

According to relevant records, before building the mausoleum, Wu Zetian asked Yuan Tiangang and his apprentice Li to help him find a treasure trove of geomantic omen. In the process of searching, Yuan Tiangang thought that the hill beside the dried and fresh quilt met the requirements of Wu Zetian, so he put a copper coin as a mark, and Li also found a treasure trove of geomantic omen and put a hairpin. Then, the two reported the news of the treasure hunt to Wu Zetian, and no one thought that something strange had happened. When Wu Zetian went to check the burial place, Jin Chai just entered the hole of the copper coin.

Wu Zetian saw this strange scene and thought it was a hint from heaven, so she chose this place as her burial place. This scene was seen by everyone. After Wu Zetian was selected, Yuan Tiangang also selected a treasure house for himself.

Ganling still follows the burial system initiated by Emperor Taizong of Tang Dynasty. Although the design of Yan Lide and Yan, the master of Tang Dynasty, was not used, the scheme of Yan Brothers was basically realized. The underground palace is still composed of three burial chambers: the front, the middle and the back, with supporting ear chambers, burial chambers, tunnels, patios and tunnels.

From the perspective of geomantic omen, Ganling has a broad vision, a very good overall environment and a strong concealment in site selection. In addition, when building Ganling, craftsmen dare not cut corners and use good materials. Even if the grave robbers find Ganling, they can't get in.
