The roaring dog in Chen Chuang's Lotus Lantern is one of the most memorable characters in all fairy tales. So many people's first reaction when they see Chen Chuang is: "Hey, isn't this a roaring dog?" Chen Chuang said that when he first heard the name, he was a little embarrassed, but he gradually got used to it. Finally, he accepted it gladly. "The audience calls you that because they recognize your role, which is an affirmation of your performance." Chen Chuang also said that it was really a big challenge for him to play this play, because he only simulated animals when he first started to learn acting, but only after taking this role seriously did he gradually realize that it was not easy for people to play dogs. We should not only try to figure out the dog's habitual little tricks, but also try to figure out the dog's psychology. Chen Chuang also did a lot of homework to play the role of a growling dog. For example, when the dog is happy, when it is angry, and when it is punished for doing something wrong, Chen Chuang studied all these and passed them on to the dog. After careful observation and painstaking research, Chen Chuang revived the mythical image of growling dog in front of the audience.
