The popularity of "Crazy" is naturally attributed to all the crew, but it is obvious that as one of the male protagonists, Zhang Yi's performance is one of the most outstanding. Even among the veteran actors, they are not inferior at all, and are even better in character interpretation to some extent.

The character An Xin has a very complex and pure growth line in the play. When she appears, her head of white hair reflects the vicissitudes of life. She has a strong sense of déjà vu, wasted years or compromise with reality, and When I was young, I could say that I was completely different from the one who had a strong sense of justice, a compassionate heart, not too much guardedness, and would be desperate and impulsive in order to investigate the case.

Zhang Yi’s interpretation of An Xin can be said to be the best. The lines, expressions or body movements at each stage are all handled very well, showing the unafraid of things when he was young. , the fierceness of gritting one's teeth, and the sense of "compromise" after wasted years, were restored and presented bit by bit, and the strength displayed is really amazing.
