I think it is more appropriate to use "Water Dragon Song". First of all, this song is pure music, without vocals, and the emotional rendering is very good, so it is more suitable for background music. Secondly, its rhythm is divided into different levels, some are high and passionate, some are deep and deep, and some are soothing and melodious. It is consistent with Chairman Mao's song "Qinyuanchun·Changsha" and feels more appropriate. Kang Zhen Qin Yuan Chun Chang Sha is a poem.
