"Sweet Le Yi" is taken from Chen Zao's poem. Le Xuan's secular literature is no good, so it's hard to meet a house in my life. The original meaning of music is stringed instrument, which is extended to pleasure. In its name, it can be extended to the meaning of Leshan, a benevolent person. Relying on means relying on, relying on, and also following and promising, which is extended to interdependence in the name.
