In fact, there are certain principles for watching candles. The grave is buried deep underground, and the air quality is extremely turbid. You can light candles to show that there is enough oxygen and no poison. On the contrary, it also shows that the air is thin and toxic, and that person must quit at the first time. As for the scenes described in novels and TV, they are only for the sake of rendering mystery, not because of ghosts.
The real story of touching a captain's gold comes from Life for Yuan Shao in Yuzhou, written by Chen Lin, who was hand-picked by Yuan Shao. Generally speaking, Cao Cao established two grave robbing organizations, Faqiu corps commander and Mojin captain, and all the stolen tombs and relics were thrown at sixes and sevens. According to the records in this campaign, this stolen tomb is probably the Han Tomb and Liang Xiaowang Tomb in Mangshan, Yongcheng. It is precisely because of these disgraceful occupations that Cao Cao supported his officers and men by stealing treasures and finally unified the North.
Although Chen Lin later complained that Yuan Shao was defeated in the face of Cao Cao, he forced him to write this campaign to frame Cao Cao. As for the truth, there is no way to verify it. With a history of more than 1,800 years ago, Cao Cao has already made up the title of the ancestor of grave robbery.
Before the demise of every dynasty in history, the tombs of emperors were looted. When the new emperor ascended the throne, he also took certain protective measures for the tombs of previous dynasties. Song Dianying of the Ming Dynasty was a veritable grave robber, who stole the tombs of Cixi and Qianlong before and after. Guo Moruo, a great writer in modern times, dug the tomb of Emperor Wanli without taking protective measures, and the unearthed cultural relics were oxidized immediately after being excavated.
