1. The mystery of Laozi's going through customs is recorded in historical books. Laozi went west to Hanguguan and was ordered to write a book in Yin, leaving behind a 5,000-word masterpiece "Tao Te Ching" in the history of China thought. Then he rode on a big green cow and went west, but there was no news. This has aroused the interest of many archaeologists and historians, but so far no conclusive evidence has been drawn. It is recorded in Zhuangzi Tiandao that Lao Zi "returned home" after leaving Zhou Shi. The mystery of life and death is the first of the four beauties in ancient China and the first female spy in China. As the protagonist of Yue, there are always different opinions about the ending of Wu's sinner stone. Some people say that Gou Jian sank into the river, and the article "Mozi Family" said: "The application of history is also beautiful." Taiping Yu Lan quoted the records of the stone in Wu Yue Chun Qiu written by the Eastern Han Dynasty: "After Wu died, the more people died in Yue Shi." The word "floating" here also means "sinking". Clothing is a leather bag. In later poems, the drowning of stone was mentioned many times. Li Shangyin's poem Jingyang Well says: "The water outside the Wu Palace is broken, and the muddy mud is still buried with stones"; Pi Rixiu's poem "Looking Back at the Ancient Palace": "I don't know where the water burial is going, and Xiyue Bay wants to be effective." This shows that in the Tang Dynasty, people recognized the saying that the stone was submerged. This is the same as the above record. Fan Li, a doctor from the state of Yue, secretly collected more folklore. However, Yuejueshu records: "After Wu's death, he returned to his teacher and swam around the five lakes with him." However, in the authoritative historical book Historical Records, although there are some detailed records, there are no words about history, and the mystery is regrettable. Some people say that he was killed by the hateful Wu people, and there is no unified conclusion in the history circle so far. 3. Xu Fudong crossed the mystery of Qin Shihuang's annexation of six countries. After the reunification of the whole country, Qin Shihuang was in a high position, and what he wanted most was to live a long life. Later, he heard that there were fairy birds in Penglai in the East China Sea, and there were ganoderma lucidum that could live forever. He sent Xu Fu to lead 500 boys and girls and 3,000 craftsmen across the sea. Later, Qin Shihuang did not expect to receive a letter from Xu Fu until his death. Where did Xu Fu go? Some people say that the navigation skills were poor at that time, and they were all wiped out in a big storm. Sima Qian first recorded the history of Xu Fu in Historical Records, but did not explain where Xu Fu drifted. Xu said in The Origin of the Japanese Nation that during the Warring States Period and the Pre-Qin Period, a large number of people immigrated to Japan along the southeast coast of China, and the boys and girls led by Xu Fu were one of them. "It must be true that Xu Fudong crossed the sea." Hong Kong Wei Ting wrote "Xu Fu's Entry into the Founding of Japan", arguing that Xu Fu was the founding emperor of Japan, Xuan Di Nakata, and the 29th grandson after Zhuan Xu. Taiwan Province scholar Peng's book Xu Fu is Emperor Jimmu further enriches Wei Tingsheng's viewpoint. There is no convincing answer to where Xu Fudong went in the vast sea of people. 4. The Mystery of Yang Guifei's Life and Death Yang Guifei is a household name in China. Her legendary life inspired the talents of countless poets and writers, and she wrote poems for them. However, what is the fate of this beautiful woman? According to historical records, in June of the fifteenth year of Tianbao (AD 756), Luoyang fell, Tongguan fell, Xuanzong of the prosperous Tang Dynasty fled with other ministers, and his beloved concubine Yang Guifei died in Mayi. However, there is a difference of 108 thousand miles between the ode of the literati and the account of the historian, so there are still many questions about Yang Guifei's final destination. 5. The Mystery of Song Taizu's Sudden Death In 960, Zhao Kuangyin launched a mutiny in Chen Qiao. In 17, he became emperor and died in 976. There is no clear record of his cause of death in the official history. The relevant records in the History Book of Song Taizu are only two simple sentences: "The emperor collapsed in the Hall of Long Live and was fifty years old." "It was ordered by Du Taihou and passed to Taizong." So his death has always been a mystery, leaving another unsolved case in history. 6. The mystery of life and death in Wen Jian, Ming Taizu After Zhu Yuanzhang's death, Judy, the prince of Yan, rebelled against the imperial court in the first year (1399). Judy was succeeded by the prince in four years, which lasted for four years. Just when Judy invaded Nanjing, the Nanjing Palace caught fire and his whereabouts were unknown. Since then, rumors about fleeing are endless, and Ming has always been uneasy about it, which has almost become a heart disease for him. For hundreds of years, the whereabouts of Emperor Wen Jian has been a historical unsolved case. To sum up, there are two main theories: "burning to death" and "fleeing".
