"Xi Ge" is a folk chant based on the wedding sequence in Tancheng, which is rigorous, natural, neat and perfect in structure. It can be divided into ten sections: leaving a boudoir, bride coming to the door, new people becoming popular, reaching out to cash in, fighting for money, worshiping heaven and earth, meeting new people in the bridal chamber, inviting new people in the bridal chamber, toasting and spreading accounts.
