This play is very interesting except for its dramatic conflict story and remarkable acting skills. An eagle-eyed audience found that Liu, a youth group of the Times, actually made a guest appearance in this play in a special way.

There is a scene in which a female high school student hangs Liu's signboard on her backpack, or the one who was scared to cry when she went to the secret room as a child.

Although it was only a flash shot, it was discovered by many viewers who watched the play with eight times the mirror. In particular, the year of the play was 20 10, when Liu was only 5 years old, but the director presented his signboard as a prop in the play, which undoubtedly became an eye-catching shot in the play.

Although it was only a moment, not even a clear shot, Liu's alternative guest appearance still excited fans: "Haha, I didn't expect to see Liu in so many plays!" "Not to mention, I didn't even know he had a guest appearance in a TV series." "Hahahahaha, the surrounding area is filming before me."
