Excuse me, who is Brother Confidence? What does he do?

At the audition of "Stand Out" last week, Yang Cheming from Hengyang expressed his dissatisfaction angrily because of the sharp comments of the judges, and threatened that if he had an advertising team, he could make the best advertisement in China, and was named "Brother Confidence" by the audience. Dissatisfied with the evaluation of the judges, "Brother Confidence" repeatedly retorted, "I don't agree with you that my Mandarin is not standard!" Yang Cheming on the stage was very angry because he refused to accept the sharp comments of the judges. He said this sentence three times in a row. Yang Cheming, a 32-year-old freelancer in Hengyang, signed up after watching Stand Out on TV. I believe that the advertising genius is looking forward to meeting Bole, "Don't pee anywhere in a small place". Yang Cheming didn't do too many performances, but spoke his own public service advertisement words by oral broadcast. He said that he had brought more than a dozen such advertisements, but the judges didn't give him enough time to finish them. But the judges didn't appreciate his advertising words. Judge Li Wei thinks that such advertising words are more suitable for slogans. "If I have an advertising team behind me, I can make the best advertisements in China." Yang Cheming said. He told reporters that "Stand Out", a stage with no threshold, allowed him to show his advertising talent, and Yang Cheming was very much looking forward to his talent being discovered by Bole.
