Born in Dong'a County, Kim Jeju Prefecture, Cheng has loved dancing knives and guns, practicing martial arts, and is good at horseback riding. In the late Sui Dynasty, the civil war was uncertain, there were many rebel armies, and at the same time, there were many mountain thieves who disturbed people's livelihood. In order to protect the fathers and elders of the villagers, Cheng Yaojin organized a defense army of hundreds of people in the local area to eliminate thieves for the people. Although the current TV role of Cheng Yaojin is from the cold door, from the childhood to chop wood for a living, but this is not the truth, but for the dramatic effect of the adaptation. According to the records on Cheng's tombstone, Cheng actually lived in the family of a minister who had been an official for generations since childhood. It is a well-known local family, educated from an early age, and is not a reckless man who only fights and kills. But his title of "Chaos Demon King" is true. It is no wonder that he used a three-plate axe to hit the world, relying on his true ability.
Cheng's tomb was discovered by archaeologists in 1986, when the coffin was opened, there was nothing of value left inside, only an epitaph still standing there, on which was inscribed the life of Cheng Biting Jin. Many of them are different from those broadcast on television.
The tombstone records that Cheng Yaojin joined the Wagang Army against the Sui Dynasty army, and made many military achievements and became famous. Cheng Yaojin also did not become emperor as it was on TV, and he was at most a powerful subordinate of Li Mi. However, later, the Wagang army was suppressed by Wang Shichong, and Cheng Yaojin was willing to surrender and was made a general. However, Cheng Yaojin did not want to work under this hypocrite, so he found an opportunity to defect to Li Shimin. With his own skills, Cheng Biting Jin was gradually reused by Li Shimin and repeatedly performed miracles. In the end, he was also named the Duke of Lu and the Grand Commander of the March of onion Mountain Road. Xuanwumen Time Cheng Jin was also one of the heroes, ranking 19 lower among the twenty-four heroes.
After Li Shimin's death, Cheng Yaojin also dutifully assisted the crown prince Li Zhi, and in order to protect the prince's safety, he continued to guard the door for three months. Legend has it that Cheng Biting Jin lived for more than a hundred years, experienced the rule of Wu Zetian, and was also known as the Elder of the Four Dynasties, because he was cautious and sleek, so Wu Zetian has not been able to kill him. Is this really the case?
In fact, Cheng Yaojin had already died in 665 AD, and he lived to be 77 years old, not more than a hundred years old, when Li Zhi was still in charge of the government. There was no life to the Wu Zetian period at all, which was also recorded on the tombstone of Cheng Yaojin, and the history books did not clearly record it, so many people misunderstood before and did not want to be deceived by the TV series anymore.
