Zhang Fan woke up and found himself sitting on a spinning chair, becoming a coach on the show 'The Voice'.

Just treat it as a dream, still very moved when I wake up..."He didn't know what happened, but he had turned his chair around.Host: "Teacher Zhang Fan, may I ask why you turned around? Are you very appreciative of this contestant's rap?"Zhang Fan: ???Host: "Please give some comments on this contestant!"Zhang Fan usually only went to karaoke, how would he know how to comment on music? He didn't even know what the musical notes were, but fortunately, he knew about 'The Voice'...
