In fact, the name of this sword has not been passed down to later generations. In Guangya, a snake named Bao was recorded. Wang Niansun has been verified in sparse evidence. ; Emperor Gao Han's sword cut off the snake and decorated it with seven pearls and Jiuhua jade. The blade is often frosty and snowy, shining on people. The cover is 0755. He believes that this broken snake was used by Emperor Gaozu to cut the white snake with a three-foot sword, and Xijing Zazhu only asked Emperor Gaozu to cut the white snake with a sword. It is said that every twelve years, the blade will be polished once, and it will always be covered with frost and snow. ;

As for the so-called Chi Xiao, it comes from a book called Guangya, which has long been lost in history. I-I've seen the current version, and the content is not ancient brushwork at all. It is easy to conclude that it was forged by later generations, so it is not credible.

The story of the drunken decapitation of the white snake by Emperor Gaozu is a hint to Liu Bang. At the end of Qin Dynasty, when Liu Bang was in Mangdang Mountain, he got drunk one night. Passers-by reported that there was a big snake in front of him blocking the road. Liu bang is in a gloomy mood and seems to be afraid of nothing. He waved his sword and split the big white snake in the way. An old woman was crying where the snake was killed. Someone asked her why she was crying. The old woman said that someone killed my son, and someone asked, why did you see your son killed? The old woman said, My son Betty turned into a snake and was hacked to death by Chi Di because he was in the way. ; Later, someone told Liu Bang about it, and Liu Bang was secretly happy and conceited.
