Wu folk songs and ballads are collectively called "Wu songs", which are an important part of Wu culture. Wu songs originated in the southeast of Jiangsu Province. They are folk literature and art with strong national and regional characteristics, and have a history of more than 3,200 years. Wu songs include "songs" and "ballads". From the content point of view, they include love songs, labor songs, current affairs songs, etc.; according to the musical form, Wu songs have six types of music, such as life whistles and Wu sounds. The folk song form with unique characteristics in Jiangnan, Tianshan songs, is also a type of Wu songs. They are mainly concentrated in the four suburban counties of Liantang, Zhaoxiang, Jinze, and Shangta in Qingpu, Shanghai, as well as Wujiang, Wuxian in Jiangsu, and Jiashan and Jiaxing in Zhejiang. Shanghai Tianshan songs are sung by farmers when they weed and plow rice. The form is one person leading the singing and everyone takes turns singing. They are also called "selling folk songs", "falling rice songs", and "big head folk songs". Shanghai Tianshan songs have a high and loud tone, free melody ups and downs, and have a large number of dragging tunes and polyphonic forms. The lyrics mainly come from the real life of the local people, mostly showing the people's labor, life, thoughts, love, etc., and are important materials for observing the social life, customs and folk customs of Shanghai and surrounding rice-growing areas. Wuxi Dongmeili area and surrounding areas are also one of the main places where Wu songs are spread. Since the Ming and Qing Dynasties and the Republic of China, Wu songs have been most prosperous in Dongting, Chaqiao and Anzhen areas of Wuxi County, and there are often folk song activities. After the reform and opening up, Wu song workers and enthusiasts in Xishan District collected, sorted and published (published) a large number of short and medium-length Wu songs and more than ten long narrative Wu songs through census. Among them are "Xiao Qingqing", "Xue Liulang", "Chen Wa Pian", "Jin Buhuan", especially the long narrative song "Shen Qi Ge", which caused a strong response at home and abroad after its publication. Wu songs vividly record the life history of the lower class people in Jiangnan and are very valuable folk cultural heritage. Nowadays, with the leapfrog development of productivity and the transformation of production relations, the number of singers who inherit Wu songs has sharply decreased, and protecting Wu songs has become a top priority.
