Several times a week, kung fu teacher Ren Ruzhi enters a ring to spar with a bovine opponent around five times his weight and capable of killing him.
Ren's mixing of martial arts and bullfighting worries his mother, but the 24-year-old has never been hurt. Besides, he says, grappling with a snorting bull is exciting.
"It symbolizes the bravery of a man," said Ren in an interview in Jiaxing in China's Zhejiang province.
