Chu songs were popular from the end of Qin Dynasty to Han Dynasty. Mainly because Chu songs originated from abroad, and since the Warring States period, the vast areas from south to Jianghuai, north to southern Shandong and east to the sea have all belonged to the territory of the State of Chu. The main military forces of Liu Bang and Xiang Yu are basically from Chu State, and most of their songs are "Chu Songs". For example, Xiang Yu has Gaixia Song, Emperor Gaozu Liu Bang has Qi Lady Song and Da Feng Song, and Emperor Gaozu Liu Che has Qiu Feng Ci and Zanzi Song. Among them, Liu Bang's Song of the Big Wind is the most famous.
Based on this, we can roughly infer the characteristics of Chu songs-using the word "Xi" in Chu sounds, imitating Chu songs horizontally in sentence patterns, mainly in seven words and four languages.
