To the east of Nanjing is the dragon-like Zhongshan Mountain, and to the west is the towering and eyeing stone city. This is the "tiger sitting on the dragon plate"
"The dragon and the tiger live in a tiger's house" only appears in Wu Dong, the Three Kingdoms. This man is Zhuge Liang. This sentence can be found in Jin's Taiping Magnolia Volume 156: "Liu Bei once sent Zhuge Liang to Beijing, and when he saw the mound of Moling Mountain, he sighed,' There is a dragon board in Zhongshan and a tiger in Shicheng, which is the residence of the emperor.' After that, Sun Quan listened to Zhuge Liang and Liu Bei's advice and moved the capital from Wuchang to Nanjing. Wu Dong, the first dynasty in Nanjing history, was born.
Zhuge Liang is a master of Feng Shui. Nanjing has a dangerous terrain, surrounded by mountains, high in the north and low in the south, which is easy to defend and not easy to attack. Qinhuai River flows into the river in the west, and there are many stone mountains along the river. From southwest to northeast, there are Stone Mountain, Maanshan, Wangsi Mountain, Lulongshan and Mufu Mountain, the highest peak of Ningzhen Mountain in the northeast, Fugui Mountain, Zhoushan Mountain and Jilong Mountain in the north, and sandbars such as Zhou Changming, Zhanggongzhou and Egret in the south, forming Jiajiang River. These natural barriers guard Nanjing and make the rulers pay attention to this treasure.
