He recorded: There is a saying: "Brother Zhang, Brother Li, we all work together to drag." Another saying: "One rest, two rest, the moon is shining on Jiuzhou." His voice was sad, and he sang in harmony. The poet was inspired and wrote seven poems called "Bamboo Branch Ci". One of the poems says: "The moon shines crookedly on Kyushu, some families are happy and others are sad! Are you worried about killing people to deal with menstruation? You have to take a rest and rest." The second line of this poem should also be the lyrics of the boat people. The folk song "Yuezi Wanwan" was still sung in various places until liberation. I don’t know what kind of tune it was sung in the Song Dynasty, but what Yang Wanli heard was “the sound is sad and melodious, and the song is harmonious to everyone”. Not many music scores of Song lyrics have been handed down. In the early years of the Southern Song Dynasty, the lyricist Jiang Kui was not only good at writing lyrics, but also good at composing music. There are 17 musical scores (Gongchipu) of his lyrics handed down (14 of them are his own compositions). After Yang Yinliu translated them into modern music scores, we can hear the melody of Song lyrics. "Sanqu" in the Jin and Yuan Dynasties is divided into two types for Zaju: Xiaoling, which is matched with "Zhiqu" (single song); Taoshu, which is matched with a suite composed of several pieces of the same palace tune. Both Sanqu and Zaju inherit some lyrics and tones.
