Juan Vasquez leads his students in tai chi practice in a park in Lima, Peru, on Saturday. Vasquez, 63, has traveled to Henan in China more than 20 times to learn tai chi since he was 17. He became a disciple of famous tai chi master Chen Zhenglei in 2011 and has taught more than 100 Peruvians to practice tai chi. He said an increasing number of Peruvians are practicing tai chi to improve their health, but he wanted to help them practice the form of martial arts correctly.  Xinhua
