Why is Nanjing called the dragon plate of the tiger?

Nanjing is called "the dragon on the back of a tiger" because of its special terrain.

Zhuge Liang sent messengers to Wu Dong, passing by Jinling. When he saw the terrain of Jinling, he couldn't help admiring: Longpan in Zhongshan, Shi Hu, the residence of the emperor. Zhongshan is like a dragon, and the rocky mountain crouches tiger, guarding Nanjing's status as king. Dragon and Tiger refers to the terrain, and it is precisely because of the special terrain that Nanjing is called "the dragon plate of tiger life".
