According to historical records, Lao Tzu went to Hangu Pass in the west and was ordered to write books in Yin, leaving 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.

Some people say that he went to India through quicksand, and I went to India to preach and taught a great disciple like Sakyamuni. Many people in the past dynasties thought that this statement was just made up by Taoism in order to raise itself and belittle other religions.

Some people say that Lao Tzu settled in Lintao, Gansu Province in his later years, and taught retired elders to refine inner alchemy, maintain health and cultivate monasticism. After gaining the Tao, he "soared" on Lintao Transcendental Platform. Others made wild guesses, saying that the law and order was poor at that time, and someone might rob halfway, resulting in accidental death.

2. The mystery of life and death in history

Shi 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 Qin Shi" said: "The Shen of the stone ("Shen ",the ancient" Shen ") 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.

3. The mystery of Xu Fudong's crossing

After Qin Shihuang annexed the six countries and unified the whole country, he lived in a high position and hoped for a long life. Later, he heard that there are Penglai fairy birds in the East China Sea, where there are Ganoderma lucidum, which can live forever. He sent Xu Fu to lead 500 boys and girls and 3,000 craftsmen across the sea. Later, Qin Shihuang never expected 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. Later generations thought it was Taiwan Province Province or Ryukyu, and some people said it was America, but most people thought it was Japanese.

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. One view is that Yang Yuhuan may have died in a Buddhist temple. The Biography of Yang Guifei in Old Tang Dynasty records that after the imperial generals Chen and others killed Yang's father and son, they strongly demanded to be executed on the grounds that "future troubles still exist". Tang Xuanzong had no choice but to bid farewell to the imperial concubine and ordered it.

5. The mystery of Song Taizu's sudden death.

In 960, Zhao Kuangyin launched a mutiny in Chen Qiao. He became emperor in 17 and died in 976. There is no clear record of his cause of death in the official history. There are only two simple sentences in the history of the Song Dynasty: "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. One view is that Song Taizong "killed his brother in order to seize this position". People who hold this view believe that Song Taizu died suddenly in the sound of a candle shadow axe, while Song Taizong stayed in the Forbidden City that night and acceded to the throne in front of the coffin the next day. It's really hard to get rid of his brother.

Another view is that Song Taizu's death has nothing to do with Song Taizong. Those who hold this view cite Sima Guang's Su Shui Ji to defend Song Taizong. According to "Shui Shui Ji", after Song Taizu's death, four drums were singing together. After the Song Dynasty, people were sent to the palace to call Zhao, the fourth son of Mao, but messengers were sent to Kaifeng.
