Why are dragons everywhere in Nanjing?

According to the ancient philosophy of China's Four Elephants Theory and Feng Shui Theory, the East is a dragon and the West is a white tiger. The eastern suburb of Nanjing is purple mountain, which looks like a dragon pan, and the western suburb is a stone city, which looks like a tiger. Zhuge Liang commented, "Zhong Pan, Shicheng is the home of tigers and emperors." Therefore, Nanjing is located in Longpan, and the two main roads of Nanjing, the city and the east, are named Longpan Road and Huju Road respectively.
