Why didn't Wu Zetian's tomb be dug up?

In the first year of Hongdao, Tang Gaozong (683), Wu Zetian appointed Wei Daijia, an official of the official department, to be in charge of the Fuling project, and Li Zhi was buried in August the following year. Since then, the Fuling project has continued. In May of the second year of Tang Zhongzong Shenlong (706), Emperor Li Xian was buried. The year before last, Tang Zhongzong also pardoned the royal family who were persecuted to death because of political problems during the reign of Wu Zetian, and reburied them, including Princess Li Xianhui of Yongtai, Prince Li Zhongrun of Yide and Prince Li Xian of Zhang Huai. In addition, in the second year of Shenlong (706), the tombs of Li, Li and Yiyang Princess Li were built.

According to Tang Yao Hui, in the 14th year of Zhenyuan in Tang Dezong (798), when Ganling was rebuilt, 378 houses were built.

At the end of the Tang Dynasty, the Huang Chao Rebellion happened. Huang Chao used 400,000 troops to rob Ganling, but dug a ditch more than 40 meters deep, without finding the entrance to the pyramid-shaped mound. Up to now, there is still a deep ditch named "Huang Chao ditch" on the west side of the main peak of Liangshan.

During the Five Dynasties, Wen Tao organized troops to excavate all the tombs of the Tang Dynasty in Chongzhou, Houliang. "The tombs of the Tang Dynasty in its territory will be found and taken away as treasures. ..... but Ganling wind and rain can't be sent. " Ganling was spared because of its strong building.

In the early years of the Republic of China, warlords scuffled, and stealing ancient tombs became a common practice. Under the guise of protecting Ganling, Kuomintang general Sun Lianzhong led his men into Ganling and used live ammunition to cover a division's troops to rob Ganling. The soldiers bombed many places with explosives, but they couldn't find the entrance to the grave.

1958, several local farmers shot and blew stones, and accidentally blew out the tomb door. 1February, 960, the "Ganling Excavation Committee" was established in Shaanxi Province. After preliminary excavation, it was confirmed that the bombing site was an underground tomb, and the excavation of Ganling underground tomb began on April 3. /kloc-in may of 0/2, the stone masonry of the tomb was all made public. The excavation situation is the same as that recorded in the Biography of Yanshan Temple in the Old Tang Dynasty, "The gate of Ganling Xuanque was blocked with stone, and the stone gap was fixed with cast iron".

Zhou Enlai, Prime Minister of the State Council, gave instructions on the excavation plan of Ganling. "We can't finish the good work, but we can leave it to future generations.". Later, the State Council issued a notice asking "Don't dig in front of the National Imperial Mausoleum", and the excavation of Ganling stopped.

Many experts believe that Ganling is the only tomb among the eighteen tombs in the Tang Dynasty that has not been excavated, because the tunnel in Ganling is complete and no new stolen caves have been found.
