Du Fu's poem said: "The silk pipes in Jincheng are full of sun, and the wind half enters the river and half enters the clouds. This song should only exist in the sky, and it can be heard several times in the world." If we don't limit the time to the Tang Dynasty, but limit the location to Jincheng (Chengdu), then, this poem is a true portrayal of China's long-standing and beautiful music.These music, along with Jiangfeng Baiyun, have been flowing to the present and all over the world.
