The first is to convey information. Yao people use ballads to send messages to each other and write letters to distant relatives and friends or lovers, which Yao people call "believing in songs". Among the Yao people, this form of communication has a long history, which is a unique product of Yao history and society, and is related to the long-term frequent migration of Yao people. The content of "believing in songs" is rich and colorful, some reflect the dark rule of the old society, some reflect the migration of Yao nationality in history, some are used to find lost brothers and sisters, some reflect the free love of young men and women, and so on. Another outstanding feature of Song of Faith is its openness. Belief in songs is not secret. During the slack season or the Spring Festival, whenever Yao people visit relatives and friends, they can open it and sing in any stockade to achieve the purpose of mutual communication and friendship. Secondly, love life. Yao folk songs are the main way for young Yao men and women to express their feelings and communicate their hearts. All the young men and women strung the stockade together and performed duets in the evening. If you fall in love with this song, you will order it privately for life. Some famous poems describing love are regarded as quatrains in Yao ballads and are often quoted by men and women in love songs. For example, "Love flowers are like ink * * * paper, and paper will rot into mud ink." "Falling in love with a sister is like winding a tree with vines, and cutting off the roots of vines is inseparable. The vine is dead, the tree is dead, and the tree is dead. " There are many such sentences in Yao ballads, which are like bright pearls embedded in the treasure house of Yao folk culture. The third is holiday blessing. During the Spring Festival, if there is a wedding, housewarming, birthday or distant guests go home to visit relatives, the host family will try their best to invite many singers to sing folk songs in pairs. Singers usually sing duets according to the arrangement of the host or the free combination of two men and two women. They sing a few songs to bless their hosts first, and then they can play freely and sing whatever they want, as long as it can add a festive atmosphere to their hosts. The fourth is the role of abstinence. "Du Jie" is a rite of passage for Yao men, which is mostly held before the Spring Festival. Every procedure in the ceremony must be accompanied by a folk song. The content of folk songs is handed down by predecessors, which embodies the content and purpose of this program. Therefore, there is a saying that the law is incomplete. For example, when Master led the ordained disciples to dance "Towards Korea" during fasting, Sang Song said, "Thank you Master Xuan for your understanding. Xuan Shi quoted the master and set out on a journey before he met the emperor. Walking in the seven stars, leading the ten temples in Kyushu. After nine days of merit, Yin and Yang teachers will see the new official. " The content of this ballad truly reflects the real content of the procedure of "going to the DPRK". The fifth is the role in the wedding ceremony. If folk songs are just a foil in Warning, then folk songs are the highlight of the wedding ceremony. All the wedding procedures are completed in the form of folk songs. If the wedding procession arrives at the woman's house, it is not allowed to sit casually. We should sing the song "Asking for a seat" to ask for a seat. For example, "butterflies are dancing on the rocks, and I don't know where I live." The octagonal balcony is full, where to hide the bird forest Please show me where the doorman doesn't sit. The deep fish in the pond like to live here, which makes the officials very unhappy. At this time, the wedding representative should thank the bride's parents with folk songs and sing: "Marry the dragon, leave the East China Sea and swim to beach after beach. Don't leave your parents to find your own way. In the middle of the month, Chang 'e matches Nanshan. I offended Gankun's parents in order to find a way out of my old life. One thanked Gan Kun for his hard work, and the other thanked the nine parents in front of the hall. The unique duet form of Yao folk songs shows Yao's profound historical culture and simple national characteristics. Yao folk songs have distinct personalities and are an important part of building a big province of national culture.
