For more than 300 years, Jingnian was the economic, cultural, political and military center of China at that time, the first city with a population of over one million in the world, and the largest city in the world at that time. During the Six Dynasties, Jiankang Palace was built. The magnificent palace was imitated by the capitals of the Northern Wei Dynasty and East Asian countries, which deeply influenced the shape of palace buildings in later generations.
Historical evolution of healthy cities
In the thirteenth year of Jian 'an in the Eastern Han Dynasty (208), Zhuge Liang sent an envoy to Jiangdong and said to Sun Quan, "The Moling Mountain is located in Longpan, Zhongshan, and Shi Hu lives in it."
In the seventeenth year of Jian 'an in the Eastern Han Dynasty (2 12), Sun Quan built a stone city, which was renamed as Moling (now Nanjing) Jianye, meaning "the great cause of establishing the emperor" (another meaning is "meritorious service").
In the first year of Huanglong in Soochow (229), on May 23rd, the sun rose and Jianye (now Nanjing) was established as its capital. He lived in the former general's office and was named "Taichu Palace". Later, a palace wall was built around it to strengthen the defense.
In the first year of Taikang in the Western Jin Dynasty (280), Jianye, the capital of Soochow, was captured by the Western Jin Dynasty and Soochow perished. Sun Hao, the last emperor of Soochow, surrendered to the Western Jin Dynasty, and the Three Kingdoms period ended.
In the third year of Taikang in the Western Jin Dynasty (282), the reconstruction industry was Jianye.
After the Eight Kings Rebellion in the first year of Yongjia in the Western Jin Dynasty (307), Si Marui listened to Wang Dao's suggestion and moved to Jianye.
In the first year of Jianxing in the Western Jin Dynasty (3 13), Jianye was changed to Jiankang because of avoiding Emperor Sima Ye. Nanjing was named Jiankang from then on, and it remained unchanged until the end of the Southern Dynasties.
