An online viral singer who became famous with one cheesy pop song that has been used millions of times as background music. He has hundreds of thousands of devoted fans who call themselves the Xu Army. He went to the Tomato Music Festival expecting the closing slot but was upset when Gu Yanqiu was given forty minutes instead. He posted three consecutive essays accusing the festival of being unrighteous and ungrateful, called fans family, and led an online boycott. His actions earned him a bad reputation in the industry. He has mediocre singing skills and zero professional ethics according to the artist director.
