69869 Haining           Discovered 1998 Sept. 25 by the Beijing Schmidt CCD Asteroid Program at Xinglong.
Haining, at the southern tip of the Yangtze River in northern Zhejiang province, enjoys profound cultural resources. It is famous for its strong leather industry and spectacular view of the Qiantang River Tide from the city itself. This extraordinary surging tide is a world-renowned natural wonder, also called Haining Tide.
