Does anyone know anything about Yunnan folk song "Three Stamps"?

Yi dance, according to legend, during the Three Kingdoms period, Liu Bei fought against Cao Cao and suffered repeated defeats. Later, due to the advice of strategist Xu Shu, Cao Cao fled in defeat. Cao Cao wanted Xu Shu, but he was worried all day. A counselor suggested: "Xu Shu has only one old mother in the church, and Xu Shu is a dutiful son." As long as her mother is invited as a hostage, her mother will write and call Xu Shu back, and she will have to go back. However, Xu's mother bravely resisted and refused Cao's request. The counselor also made suggestions, saying: Xu's mother wrote "Plum Blossom Seal" by hand. She only had to copy her font and write to Xu Shu, saying that her mother was dying and she was not afraid that Xu Shu would not come back. This move really worked. Xu Shu read the letter, resigned from Liu and returned to Cao. Liu reluctantly sent ten miles and ten miles. When Xu Shu's distant figure was covered by trees, Liu Bei ordered the soldiers to cut down the trees, and ordered the soldiers to shout and dance in unison to bid farewell to the strategist. Cao Cao also cheered the soldiers and welcomed Xu Shu back. Later, people put the touching scenes of two families in Cao Liu, one welcoming and one delivering, into a cloth jump, and then evolved into today's three stamping. And the touching scene of Liu Bei's farewell to Xu Shu was repeatedly sung as an episode, that is, "Uncle Wang contended and Uncle Xu walked away". Three stomping feet are also called "dancing lusheng", "dancing three strings", "three-legged song" and "dancing song" It is a folk dance widely popular in Sipu area, especially in rural areas, and is deeply loved by people of all ethnic groups. Dance three times on holidays, or on major happy occasions. Three stamps are generally organized by groups or individuals and are usually held at night. First set a table at the meeting place, put tobacco and alcohol on it, burn a fire cage, and let the specially invited village stringer accompany you in the middle. People form a circle and stomp their feet in circles according to certain movements. If it is during the Spring Festival, people will naturally gather in a wider place in the village, build a fire cage in the field with firewood collected by everyone voluntarily, dance around the fire cage, and enjoy the tobacco, alcohol and food collected by everyone. Jumping and stomping three times often lasts for several nights, and staying up all night at the busiest time. According to local customs, some are accompanied by Hulusheng, some by Xiao Sanxian, and some by Bilu, Suona, citronella and other national musical instruments. Accompanied by Hulusheng and Xiao Sanxian, it is often called "dancing Lusheng" or "dancing Sanxian". Generally, it's a title word, and everyone sings along with it. The subject word is usually improvised, seven words and four sentences, and generally rhymes. The lining word is "Uncle, look, hey, Xu Shu, yo, hey". Three stomping words can generally be divided into five types: new folk songs, arranger, guessing songs, Sanqu and antithetical songs. New folk songs are folk songs produced in the new society, including singing praises to the party, socialism, the motherland, the new life or lashing out at all social unhealthy practices and ugly behaviors, and persuading people to be kind. The arrangement of songs is to integrate astronomy, geography, history, production and life knowledge, ancient and modern stories, celebrity philosophy, etc. into it in the form of narration, giving people the function of warning and education. Guessing songs is a brain game, which aims to teach social knowledge of nature through riddle-like questions and answers. Sanqu refers to the improvisation in Sanyinchang, which occupies a considerable proportion in Sanyinci. The duet is the most lively part of Sanshou, and it is also the climax of Sanshou, which most people can cope with. Among them, the duet of male and female love songs is the most wonderful, and the lyrics are also the most rich and touching, which often becomes the medium of love between men and women. Listen, hey, hey, hey, hey, hey, hey, hey, hey, hey, hey, hey, hey, hey, hey, hey, hey, hey, hey, hey, hey, hey, hey.
