After somersaults and handstands, little kungfu champion Li Zhongzhou falls to the ground like a drunken man. Moments later he jumps up and leaps into the air as he strikes various moves.

Nicknamed "little Bruce Lee", the 11-year-old champion of many national martial arts contests was comparing moves with classmates during an interval between classes in Tangshi Primary School in Zhangjiagang city, eastern Jiangsu province.

"We picked up martial arts at our school and I have been learning for two years," Li said, timidly bowing his head. That's when his father came to work as a porter in Zhangjiagang.
