On the September 8 edition of MBC pilot variety program, 'Tutoring Different Generations,' Jung Jun Ha and Heechul sat down to learn Chinese from rookie singer,Z.HERA.

Jung Jun Ha asked him, "Super Junior is very popular in China.  Among the members, how popular are you?"

Heechul said confidently, "I am really popular in China.  I can't lose China.  When I promote in China, my hair is long and I show a pretty self.  At the time, I'm really popular because there are no pretty male celebrities in China.  If I go to a Chinese airport, 500,000 Chinese fans come out to see me," while Jung Jun Ha looked skeptical at his comment.
