Speaking of cooperation with the famous director Ying Da, Mars said that he has cooperated with Ying Da for nearly 500 episodes of sitcoms from his first sitcom "Spring is Suddenly Released" to "A Family in Northeast China", "Lilac bloom" and "Happy Telecom Street". "It's a great pleasure to work with Ying Da on filming. He is very humorous. Every time he shoots, no matter who brings up a funny topic, he will definitely pick up the words and chat with everyone. What he says always makes everyone laugh. Sometimes after talking for a long time, he suddenly said,' Oh dear! Off topic, hurry up! Because we always shoot in such a pleasant atmosphere, it is easy to get into the play when shooting sitcoms. Another happy thing about working with Ying Da is that you will never feel pressure to lose weight. I tried to lose weight while filming Happy Telecom Street, but he resolutely stopped me. Ying Da is a person who doesn't support losing weight, so he won't let any actor who works with him lose weight, and the actress who works with him has no pressure to lose weight. He is so greedy that everyone eats like crazy with him. As a result, everyone in the crew gained weight and had an' English chin'. "
