Cheng Long: When I first knew that I would shoot the advertisement of "Brother Chun Gang", I actually rejected it. Because I think, you can't ask me to shoot and I will shoot immediately. First, I need to believe in it, and I also want to say, if you are a gang, after believing in it, you shout out many slogans, such as "Believe in Brother Chun, no traffic jam", "Believe in Brother Chun, eternal life". The audience will definitely scold me because there is no such thing as "Brother Chun Gang".
