Tibetans are divided into three major dialect areas: U-Tsang, Kham, and Amdo. Combined with the terrain, they form three culturally distinctive areas. Laiyi is a folk song art that specifically expresses love content, which is spread in the vast Amdo dialect Tibetan areas such as Qinghai, Gansu, and Sichuan. Its distribution is centered on the Qinghai Lake area and the Yellow River Basin (with Hainan and Huangnan Prefectures) and radiates in all directions. Laiyi is derived from Tibetan folk songs. The division of the three major Tibetan areas in the 7th century AD promoted the widespread spread of Laiyi in the Amdo Tibetan area of the "Lower Dokang". Laiyi is rich in variety and quantity, and its content covers all aspects of love life. A complete antiphonal singing has a certain procedure, such as introduction song, greeting song, love song, love song, missing song, contrary song, separation song, and ending song. The tunes of Laiyi have formed various styles due to different regions. Some emphasize the language of music and have a relatively compact rhythm; some have deep and melodious melodies, forming a free, graceful and long folk song style; some have sweet melodies and regular rhythms, forming an elegant and dignified lyrical style. Laiyi has a long history and has grown in sync with the Tibetan people. It carries the creativity and inspiration of the nation and has important value in the research of anthropology, ethnology, folklore, etc. Laiyi not only shows distinct regional characteristics and unique artistic style, but also reflects unique and important cultural values with its rich forms of expression.
