More than 800 acupuncture needles were pierced on the head of Wei Sheng, a Chinese medicine doctor from Guang Xi, Southwestern China. He once won a Guinness World Record for piercing 1790 needles on his body in 2004. He said that his main purpose of self-piercing is to promote China's traditional acupuncture. He plans to pierce 2oo8 needles in his body as a special gift to Beijing Olympics in 2008, for which he has already reserved a hotel room in Beijing.
