I'll answer the questions raised by the questioner. I don't think the beauty of the dairy forest means anything. Since director Zhang Yimou wants Nailin to go on stage, it is meaningful to let her sing on stage. Why cheat the audience? But I think Yang had better sing on the stage. He came up with this idea, which I can only say is stupid, because it may hurt Yang's heart. Therefore, I hope that the next time director Zhang Yimou wants to continue to let Nailin or Yang perform, he will stop lip-synching.
