Huaer originated in the early Ming Dynasty (around 1368 AD). It is a folk song created and shared by the Han, Hui, Tibetan, Dongxiang, Baoan, Salar, Tu, Yugu, and Mongolian ethnic groups in Gansu, Qinghai, and Ningxia in northwestern China. It is named because the lyrics compare women to flowers. It is sung in Chinese and is influenced by the traditional music of Qiang, Tibetan, Han, Tu, and Muslim ethnic groups. Due to the different musical characteristics, lyrics and regions of circulation, Huaer is divided into three major categories: "Hehuang Huaer", "Taomin Huaer" and "Liupanshan Huaer". In addition to impromptu singing while working in the fields, grazing in the mountains, and traveling, people also spontaneously hold a large-scale folk song competition "Huaerhui" at a specific time and place every year, which has the special value of multi-ethnic cultural exchange and emotional integration.
