A group of teenagers, wearing boxing gloves, are practicing boxing skills, sweating profusely, in Zhongshan Shang Wu Club.

The 8 young boxers, aged from 15 to 17, are the top athletes picked out by Zhongshan Association of Fight, Sanda & Boxing through rounds of selection. Most of them left their parents and hometown alone since childhood, and gathered in Zhongshan because of boxing.

"The training is harsh. I usually missed my parents and once considered giving up when I first came here. But I have persevered finally, because I do want to play in professional games in the future," said the 16-year-old Wang Jiahao from Zhoukou, Henan Province.

The 5-day National Youth Muaythai Championships 2019 recently concluded. After fierce competition, Fu Kewei and Ye Jijin won the fifth place in Men's 57-60 kg and Men's 60-63.5 kg respectively. Wang Jiahao and other 5 athletes also advanced to the top 16.
