What is the background music of Mu Wang's Poems by Renzeng, the lover of Cangyang Jiacuo?

Dawa Zhuoma Cangyang Jiacuo built a beautiful pavilion called Longwangtan Scenic Resort Scenic Resort on a small island in the lake behind Potala Palace, and invited young men and women in Lhasa to sing, dance and drink together. Cang Yang Jia CuO wrote many love songs for everyone to sing. These love songs soon spread in Tibet and were deeply loved by people. In Longwangtan Scenic Resort Scenic Area, Cangyang Jiacuo met a girl from Qiongjie named Dawa Zhuoma. Dawa Zhuoma is beautiful in appearance, gentle in temperament and sweet in voice. Her big black and bright eyes are like freshly brewed wine, which can make people intoxicated at a glance. Cangyang Jiacuo and her special acquaintance and love, as if one person is the shadow of another. They sing and dance together during the day and often meet at night. Cangyang Jiacuo likes Dawa Zhuoma very much, and thinks it is a gift from heaven and the fate of previous lives. He wrote such a song to express his feelings:

Lhasa has a dense population and beautiful scenery. My soul mate is Sister Joan.

As the saying goes, sweet highland barley often leads to bitter wine, and happiness often turns into sorrow. Later, Cangyang Jiacuo found that Dawazhuoma had not come to Longwangtan Scenic Resort scenic spot for many days, and sent her a message about the treaty meeting, but she didn't reply like Baba scattered in the water. She visited her residence in person, only to find that there was a big lock hanging on the door, and asked her neighbors about it, only to know that Dawa Zhuoma had been brought back to Sister Qiong by her parents for many days. Cangyang Jiacuo felt particularly sad, as if he had lost his beloved baby. When he was driven out of his mind and bored, he wrote the song "Don't talk about knots again". Since then, Cangyang Gyatso has never seen Dawa Zhuoma again and has become his dream lover.
