In The Man Who Caught the Rainbow, he played Wu Caiyun, the heroine's half-sister. Unlike her sister Wu Caihong's sadomasochism, Cai Yun's feelings are innocent and her love is sunny. In this play, Cai Yun's sense of shame is both lovely and sweet, and it is a warm-hearted regulator outside the main line of sadomasochism. When asked about his expectation for the role of Caiyun, Liu Xiao said that the rainbow is more than just a color. He hopes to be a "sweetheart clown" in the play and bring different colors to the play.

The new drama "I just like you" Liu wears a light pink uniform, which is very pure and sweet. In this new play, Liu He has many opposite plays, playing his sister, an innocent and charming girl. Together with the heroine Qian Baobao played by Chen Qiaoen, we gradually grow up in the development of the plot, see our feelings clearly, and finally find happiness. I believe that Liu, who is full of vigor and vitality, will inject fresh vitality into this role, and together with Jerry and other beautiful men, he will create an idol drama of the warm-blooded military academy of the Republic of China.
