While Yang Yang was singing, a boy in a hat said loudly to Yang Yang on the stage: Take off a little more. Mango Taiwan turned up the stereo to cover up the noise. If you don't believe my friends, you can ask the fans at the scene. There is also evidence that Sa Dingding said after singing in Yang Yang: Although there were shouts at the scene, Yang Yang could continue to sing. And the judges also said in Weibo: Yang is the real calm sister in this situation.
