Veteran key-cutter out to catch 10,000 thieves

Like a hero from a kung fu story, Sun Yunyi seeks to help the needy every day, out of a sense of justice. Carrying a 1.5-meter-long self-made spiked club, he has caught more than 6,000 thieves in the past 42 years.

In addition to running a key-cutting store in Kunming, capital of Yunnan province, Sun, 75, has dedicated more than half his life to catching thieves.

He is only 1.65 meters tall and of medium build. However, Sun's kung fu ability sets him aside from other men his age.
