The number of imperial tombs in the Qing Dynasty is still quite large, there are Qing Dongling, Xiaoling, Yuling, etc., almost every emperor will build an imperial tomb for himself after death, and some even in their prime years have begun to build a large number of construction, because the emperors are also more worried, in case they encounter any accidents, they can't even have a place to live after death. The most famous of these, the Dingdong Tomb, is the mausoleum of Lafayette Cixi, which took a full 14 years to build.

The materials used in empress dowager Cixi's mausoleum are extremely luxurious, the inner walls of the east and west halls are inlaid with brick carving patterns, the paint on the ceiling is all gold, and 64 pieces of white jade are used, and the treasures inside are dazzling, Cixi thought that she could stay here safely and steadily, but she did not expect that someone would disturb her dreams and make a mess of her mausoleum. This person is Sun Dianying, who is not only an old warlord, but also a tomb robber.
Sun Dianying hated the Qing Dynasty flag people in his bones, his father had been imprisoned for the township head and the flag people quarreled, and was killed in prison that day, Sun Dianying was born poor, had no background to rely on, and had no relatives after his father's death, but he had a bold personality, and liked to do chivalry and righteousness like his father, and became the leader of the with his witty mind.
In 1922, he took his brothers into the Henan Army, from aide-de-camp to a nominal battalion commander, Sun Dianying monopolized the mountain and became the leader of the bandits, until the second Zhifeng War in 1924, Sun Dianying took advantage of this opportunity to recruit troops, the team expanded to thousands of people, Sun Dianying saw the qing emperor's mausoleum on the way to suppress bandits, in order to raise funds, began to start its idea.
In order not to be discovered by this tomb robbery, he made sufficient preparations, first of all, to let the nearby people hide far away, and demarcated a certain area, saying that it was to carry out military exercises. There is also the transfer of the treasure, he told the local steward that the bandits need a lot of funds, and he can't bear to collect from the local, planning to borrow 30 cars and horses to transfer materials from elsewhere, in fact, in order to transfer the treasure as soon as possible, it is said that the craftsmen recruited are all dumb to prevent someone from leaking secrets.
After everything was ready, he did not send someone to dig little by little, but used the most direct method, using explosives to blow it up. All the officers and men present were stunned by the sight in front of them, the bricks were made of gold, and there were all kinds of other treasures. The officers and men were all happy and moved to the car one by one. Cixi's body was also damaged by Sun Dianying, and after her teeth were broken, the night pearl in her mouth was taken away.
Not only did he loot Cixi's mausoleum, but even Qianlong's Yuling tomb could not escape its clutches, and the mausoleum was also luxurious. Later, when the relevant experts excavated in the rescue, they found that Qianlong's skull was gone, and it was very likely that Sun Dianying had taken it away, and one of the reasons he did this was not for money, but because he hated the rulers of the Qing Dynasty, thinking that his ancestor Sun Chengzong died at the hands of the Qing army, and his father could not escape the same fate. There is also his tomb robbery, which has attracted the condemnation of many descendants of the royal family.
