The Black Dragon Pool (Heilongtan), which lies in the Wulao Hills, is a famous sight on the northern outskirts of Kunming. 

It is known for its 'four beauties', namely, the Han Temple, the Tang Plum Tree, the Sung Cypress and the Ming Tomb. The pool itself is extremely limpid and a jet of fountain water can be seen gushing constantly onto the surface. 

A legend says that a long long time ago there were ten dragons doing great harm to the people. 
Lu Dong-bin, one of the Eight Deities, subdued nine of them and buried them under an ancient pagoda. A small black dragon was left here and was commanded to do good to the people. Hence the name of the pool. 

Close by the Dragon Pool is the famous Yunnan Botanical Garden, also a wonderful place for sightseeing.
