Nanjing, known as Jinling in ancient times, is one of the famous historical and cultural cities in China with a long history and splendid culture. Historically, Nanjing was once the capital of the Southern Ming Dynasty and the capital of the Taiping Heavenly Kingdom, which had an important historical position. The title of "Dragon Pan and Tiger Ju" makes the city of Nanjing full of mystery and majesty. "The home of dragons and tigers, the home of emperors" comes from Zhuge Liang. 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.
He told Sun Quan that Nanjing was "the dragon of Zhongshan and the tiger of Shicheng". This statement can be found in the Song Dynasty, Li Mu, Xu Xuan and other scholars' "View of Peace" cited in Jin (volume 156): "Liu Bei once sent Zhuge Liang to Beijing, and when he saw the hill of Moling, he sighed,' There is a dragon in Zhongshan, a tiger in Shicheng, and the emperor lives there.' 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.
