Shulaibao is a traditional Chinese folk art popular in northern China. Shulaibao originated from a method used by beggars to ask for money. It is performed by one or two people. The rhythm is played with bamboo boards or cow femurs tied with copper bells. The commonly used sentence patterns are the "three, three" six-character sentences and "four, three" seven-character sentences that can be broken, and the rhyme can be changed after two, four or six sentences. At first, the artists performed along the streets, improvising lyrics based on the scene. Later, they entered small amusement parks for performance, and the content of the rap changed. Some artists sang Chinese folk legends and historical stories, which gradually evolved into fast-paced books, which became popular at the same time as Shulaibao.
