The location of the dry mausoleum of Wu Zetian was decided by Yuan Tiangang, a geomantic master at that time. Many of Yuan Tiangang's friends know that he is good at Feng Shui. The location of Wu Zetian's mausoleum was decided by him after he visited many places for a long time.
Since the completion of this tomb, when the Tang Dynasty disappeared from history, the tomb of Wu Zetian has become the target of many grave robbers. One of the most famous is Huang Chao, who once used his 400,000 troops to dig. It can be said that he has the most manpower, and even almost dug Ganling. He once dug a ditch more than 40 meters deep. Unfortunately, even with such great efforts, he still couldn't find the entrance to Ganling. The ditch he dug has now become a tourist attraction.
Another time was during the Republic of China, when warlords scuffled. One of the most famous events was Sun Dianying's excavation of the tomb of Empress Dowager Cixi. At that time, some warlords were very interested in the dry mausoleum of Wu Zetian. This man is Sun Lianzhong, the general of the Kuomintang. He once surrounded Ganling in the name of military exercises, and then bombed it with gunpowder. But in the end, he still couldn't find out where the entrance to Ganling was. Later, the intersection of Ganling was discovered by accident. It was several local farmers who wanted to blow up the stone by shooting, but they accidentally found the entrance and reported it to the relevant departments in time, so Ganling was protected. Now they know where the entrance is and they can't dig it.
