During one of the episode, Jane Zhang was invited as a guest alongside several singer such as G.E.M 邓紫琪，Jason Zhang 张杰

During the PK round, Jane Zhang and G.E.M collaborated and sang a 1998 song  "雨蝶”

This performance became popular because of the incredible singing techniques and overall its just mesmerizing!

A 16 days work with many struggles, as this is such a high level detailed drawing.
