    Zhang Kui first learned he could perfectly mimic(模仿)the sounds of animals when he was a child. The 29-year-old, who grew up in a poor family in Qiyang, Human province, today is a full-time performer of kouji.

    Zhang was 15 when his father died in 2003. He dropped out of school and joined his uncle's theater. Zhang bought CDs to study how to mimic the sounds of musical instruments and animals. He performed shortly afterward at a small theatre. “Although I wasn't that skilled, I got a lot applause(掌声). It was my first time on the stage. And then more and more audience came to watch my performances.” he said.

    He moved to Guilin in 2004, where he found work as a waiter at a karaoke bar. In 2005, Zhang went to Guangdong province and performed outside supermarkets to sell shampoo. “They paid me less, so I had to perform at bars at night.” said Zhang. He also worked as a condtruction worker. In 2007, he went to Beijing to learn from Niu Yuliang, a Beijing Kouji master. He worked as a gatekeeper to pay his way. He went to Niu on weekends and during the holidays to learn.

    Zhang's skills improved and he has since performed on more than 20 television programs. In September 2013, he was invited to Switzerland, in 2004, he performed in Africa, Europe and North America.

    Last year, he made a short film about the art and said it was the first film on the subject. The film will be on this year, and he said he hoped to draw more attention to the art. He also plans to give lectures on this traditional art at universities.
