Chen Dayu grew up in an acting family, his father Chen Peisi is a famous comedian. However, he majored in biology in college, and the word "filming" has nothing to do with it.

After studying abroad for two years, he became interested in theater and gave birth to the idea of becoming an actor. Since then he has starred in many dramas such as "Old House" and "Balcony", looking for feelings little by little, and has won a lot of audience popularity with his increasingly mature stage performance.
