Zhongshan is often surrounded by purple clouds and so it is also known as Purple Mountain. Zhongshan and Houhu are in harmony, with a foundation in Nanjing. With the trend of “Dragons”, Zhongshan stands on the bank of the Yangtze River, covered in smog, and after thousands of years, it is still covered in lush greenery.  The number of kings and heroes, pines and multiculturism were outstanding in the mountains. Amongst these are the Six dynasty culture, the Ming dynasty culture, the Republican culture, the landscape culture, the ecological leisure culture, and the Buddhist culture. It is the “first mountain of humanity in the Chinese city.”
