Shaoguan (韶关) is a prefecture-level city in northern Guangdong province, China where the mummified remains of the sixth Zen Buddhist patriarch Huineng remain. Shaoguan is located on the Beijing-Guangzhou railway about 221 kilometers north of Guangzhou. Shaoguan is also readily accessible by road as it is adjacent to the Beijing-Zhuhai freeway. At Shaoguan, the Wu River from the northwest and the Zhen River from the northeast join up to create the North River ( Bei Jiang ) which flows south to Guangzhou. The downtown part of Shaoguan is located on a peninsula between the Wu and Zhen Rivers and is a peninsula almost surrounded by water. The rivers are maintained at a constant level by a dam about 12 kilometers downstream from the city. The city has about 20 kilometers of tree-lined riverside esplanades along the banks of the rivers. There are seven bridges crossing the three rivers. The Fengcai Tower in the centre of Shaoguan was built in the Ming dynasty. To the south of the tower, at the other end of a pedestrian shopping street, the Dajian Monastery was founded in 660. Near Shaoguan is the town of Maba, home of relics and museum of the Maba Man, Chinese Neanderthals. Near Maba is the Nan Hua Temple which is supposedly the original place of Zen Buddhism about 1300 years ago. The large Shaogang iron and steel factory is also located near Maba. Near Shaoguan in Renhua county is located the Danxia Mountain which is a famous scenic area. Northwest of Shaoguan, at the town of Pingshi, a dramatic stretch of river known as the Nine Torrents and Eighteen Shoals is a popular place for white-water rafting.
