Chengdu, where Yang Xiaoyun was born and grew up, is a city full of tolerance and vitality. She loves this city with all her body and soul, loves Chengdu in music, loves Chengdu in taverns, and loves Chengdu in the birthplace of folk songs in 37° Bar. Here, there is new love and music every day. They began their youth and youth in the bustling city, drinking music and tears all night long in a tavern in winter, saying goodbye to their youth and love. Yang Xiaoyun and the folk singer Cao Li, whom she had loved for many years, had been separated for several years, but they were still deeply in love at the time of their deepest love. She left Chengdu and went to Dali to recover from her injuries, while he wandered away for love. When youth is gone, we can only feel the music and road of Chengdu again in Cao Li's singing, and in the sound of his piano, we can look back at the most youthful, passionate and rocking song of post-modern youth.
