Zhu Yuanzhang left a trick on his deathbed, deceiving the world for more than 600 years, and it still can't be cracked.

During Zhu Yuanzhang's reign, he ordered farmers to return to farming, rewarded reclamation, engaged in resettlement and military camp construction, organized local farmers to build water conservancy projects, and vigorously advocated planting cash crops and fruit trees such as mulberry, hemp and cotton. He also enriched the people, suppressed the strongmen, ordered the liberation of handmaiden and so on. After the efforts of Hongwu period, social production gradually recovered and developed, which is called the rule of Hongwu in history.

1380 (in the 13th year of Hongwu), Zhu Yuanzhang abolished the prime minister and set up three departments, namely, the Department of Publicity and Deployment, the Department of Sentencing and the Department of Provincial Judges, all of which were under their command, and the three departments were decentralized, further strengthening the centralization. 1398 (thirty-one year of Hongwu), Zhu Yuanzhang died in Yingtian at the age of 7 1. The temple was named Taizu, and posthumous title opened the heaven to establish the Great Sage to Emperor Wu Junde, and was buried in the Ming Tombs.

The Ming Tombs are located at the foot of Mount Qomolangma in Dulong Mansion, south foot of Zijinshan Mountain, Xuanwu District, Nanjing City, Jiangsu Province. Sun Yat-sen Mausoleum in the east and Meihua Mountain in the south. Located in Zhongshan Scenic Area, it is the burial tomb of Zhu Yuanzhang and his empress. It was named "Xiaoling Mausoleum" because posthumous title of Ma Shi was the "Empress of Filial Piety" and she pursued filial piety to govern the world. Covering an area of 6,543,800 square meters, it is one of the largest imperial tombs in China.

After exploration, Dulong House, where the Ming Tombs are located, turned out to be a solid stone mountain. Some tombs dig a deep hole from top to bottom and then seal it up. But the Ming tombs dug it horizontally into the mountains and hollowed out the Xuan Palace from the inside. Although this horizontal cave method is a huge project, it is very solid. Without explosives, ancient grave robbers could not dig holes from top to bottom.

The cross-hole design makes the tomb passage the only passage for grave robbers. In order to hide the tombs, the craftsmen who built the Ming tombs also tried their best. Through accurate magnetic survey, archaeologists found that the tomb passage was not in the middle as people thought, but on one side. This unconventional design has made many grave robbers return in vain.

However, after experts' investigation of historical materials and Xiaoling Mausoleum, it is found that Zhu Yuanzhang may not be buried in Xiaoling Mausoleum, but this is just his suspected tomb. Zhu Yunwen is the only one who knows the real tomb of Zhu Yuanzhang. It is said that when Zhu Yuanzhang died, he called Zhu Yunwen to his side and told him a big secret. This is what happened behind Zhu Yuanzhang. When he died, he left the world with an eternal mystery.

He asked Zhu Yunwen to attend the funeral seven days after his death, and not to wait for other kings who were not at home. At that time, due to the short time, Zhu Yuanzhang's other sons were in other places and had no time to go back to Beijing to worship. Moreover, on the day of the funeral, there was a funeral guard of honor at the thirteenth gate of Nanjing City, and the lineup was exactly the same, which was difficult to distinguish between true and false. The world and all ministers don't know which team is Zhu Yuanzhang's real funeral procession, and people don't know where Zhu Yuanzhang is buried.

As for the burial place of Zhu Yuanzhang, people have speculated that Zhu Yuanzhang was not buried in the underground palace of the Ming tombs, but in the Chaotian Palace in Nanjing, that is, the Long Live Mountain in Nanjing. The location near Xuanwu Lake is also the key suspect, and some even say that Zhu Yuanzhang has returned to his hometown. No one can be sure of the real burial place of Zhu Yuanzhang, the cloth emperor. When he died, he designed such a big conspiracy for the world. Hundreds of years have passed, and no one has been able to crack the secret so far. This may be the cleverness of Zhu Yuanzhang, who avoided the theft of the mausoleum and got a peaceful life in another world.
