The Black Zhuang is a unique group of the Zhuang people. They call themselves "Min", "Zhong" and "Ao". There are about 51,800 people now. They are named because they wear all black. They mainly live in Napo County, Guangxi, which is located on the China-Vietnam border. Napo Zhuang folk songs are folk songs that have been sung by them for generations. Throughout the long river of history, the Black Zhuang still preserves the simple, complete and colorful folk songs, and is known as the "rich mine of Guangxi ethnic music" and the "living fossil" of Zhuang folk songs. The Napo Zhuang folk songs with a long history can be divided into six categories according to different tones, namely "Sui Min", "Lun", "Ai De Ya", "Chun Niu Diao", "Qing Xian Ge" and "Pan Rui", with about 160 sets. Representative songs include "Sui Dai Ke", "Lun Zao", "Jiu Ge", "Pan Ge", "Zu Zao Song" and so on. In terms of content, Napo Zhuang folk songs mainly include narrative songs about myths and legends, biographies, environmental changes, historical events, etc.; bitter songs that express suffering and accuse oppression; farming songs that reflect nature and life experiences; songs praising beautiful scenery; etiquette songs for receiving people; folk songs that express traditional habits; sacrificial songs for mourning and funerals; toast songs to celebrate the full month of a wedding, the completion of a new house, and the birthday of the elderly. The richest are love songs, which contain more than 20 kinds of content, including lyricism, first love, love, teasing, gambling, engagement, oath, praise, lovesickness, loyalty, separation, exhortation, regret, nostalgia, reunion, bitterness, sighing, fighting, and growing old together. In the long process of development, Napo Zhuang folk songs have formed the characteristics of dependence on folk customs, relatively stable procedures, rich and colorful content, and originality. In addition to its functions of communication, publicity, education, and entertainment, Napo Zhuang folk songs also have historical, academic, artistic, and practical values. They are the remains of the ancient Zhuang folk song culture. Due to the changes in the cultural space on which they depend for survival and development, the disappearance of the main channels of inheritance, the gradual reduction of venues for activities, and the gap in the inheritance of teachers and students, the Black Zhuang folk songs are facing a severe inheritance crisis. Therefore, it is urgent to save, excavate, organize, and protect the Black Zhuang folk songs.
