What does Jianwang mean by three pure yang and five qi?

Five Qi should mean five green beans under the prefix Chunyang in the upper left corner. In addition, upstairs, Sidou can play two musical instruments. I have never played Jian Chun, but I am familiar with Qi Chun. Those five beans can increase some skill damage of Yangchun, and Qichun is mainly used to shoot two instruments, five sides, gossip, and the more beans, the better the effect. If you still don't understand, please ask.
