The pipa song "Ambush from Ten Sides" (referred to as "Ten Sides", also known as "Huaiyin Pingchu") is based on the decisive battle between Chu and Han in Gaixia in 202 BC, when the Han army defeated the Chu army. Written in a concentrated summary of historical facts.

According to the "Sizhaotang Collection" written by Wang Youding (1598-1662) of the Ming Dynasty: "When the two armies were fighting a decisive battle, the song "Chu and Han" shook the heaven and earth, and the tiled houses were like flying down. Xu Er Observe, there are sounds of gold, drums, swords and crossbows, and the sound of men and horses fighting, but there is no sound for a long time. The ones that are resentful and difficult to understand are the songs of Chu; the sad and strong ones are the sounds of King Xiang's lament and the sound of Farewell My Concubine; There are sounds of chasing horses in Daze; when they reach Wujiang River, there are sounds of King Xiang committing suicide, and the sounds of other riders trampling and fighting for King Xiang make those who hear it start to get excited, but then stop crying. These descriptions are so touching. The musical conception of "Ambush from Flying Daggers" is very similar. It can be concluded that "Chu Han" is the predecessor of "Ambush from Flying Daggers".

"Ten Faces" included in "Pipa Music" compiled by Hua Qiuping in the Qing Dynasty is the earliest version of "Ambush from Flying Daggers". In the 21st year of the reign of Emperor Guangxu of the Qing Dynasty (1895), Wang Junxi's "New Pipa Score of Thirteen Daqu Operas of the Northern and Southern Schools" edited by Li Fangyuan also included this piece and changed its name to "Huaiyin Pingchu". Although it is recorded as being composed by Qin Hanzi in the Sui Dynasty, history There is no such thing as a Qin Hanzi. Therefore, like many folk music, the author of "House of Flying Daggers" is still among the "unproven" ones.
