Amusing things about the Ming Tombs-Dingling Tombs

The Ming Tombs are the tombs of the thirteen emperors of the Ming Dynasty. The Ming Dynasty went through sixteen emperors. Zhu Yuanzhang, the founding emperor of the Ming Dynasty, established his capital in Nanjing. After his death, he was buried in Zhongshan Mountain in Nanjing, known as the "Ming Xiaoling Mausoleum". The second emperor Zhu Yunwen (Emperor Jianwen) sent troops to Nanjing in the name of "Jingnan" (meaning to relieve the emperor from danger) because of his uncle Zhu Di. Emperor Jianwen did not know where he ended up. Some people say that he became a monk, but his whereabouts are unknown (this is an unsolved case in the history of the Ming Dynasty), so there is no mausoleum. The seventh emperor Zhu Qiyu ascended the throne under the orders of the Queen Mother and ministers because his brother Emperor Yingzong was captured by Wala. After the Yingzong was released, under the planning of his close associates, he carried out a "revolution to seize the gate", restored the Yingzong, and became emperor again. Zhu Qiyu was killed. Yingzong did not recognize him as the emperor and destroyed the mausoleum he built in the Tianshou Mountain area. As a "king", he was buried in Yuquan Mountain in the western suburbs of Beijing. In this way, two of the sixteen emperors of the Ming Dynasty were buried elsewhere, one is missing, and the other thirteen are buried in Tianshou Mountain, so they are called the "Ming Tombs." Did Emperor Jianwen finally set himself on fire or escaped from a secret tunnel? Still a mystery.
