Monks practice martial art at the Quanzhou Shaolin Temple in Quanzhou City, southeast China's Fujian Province, May 13, 2015. Located in the east of the Qingyuan Mountain of Quanzhou, the Quanzhou Shaolin Temple, also called the South Shaolin Temple, is the birthplace of the South Shaolin martial art, which has spread to Taiwan, Hong Kong and Macao and even Southeast Asia since Ming (1368-1644) and Qing (1644-1911) dynasties. It's also jointly called "the South and North Shaolin" with Songshan Shaolin Temple in central China's Henan Province. Zen, the doctrine which every monk learning the Shaolin martial art should observe, refers to a frame of mind which gets rid of greed, anger and confusion and helps oneself reach inner peace as to become more powerful and invincible.
