Qiantang County was established in Qin Dynasty, but it was changed to Qiantang County in Tang Dynasty to avoid national taboos, and the name of Qiantang County was retained until the early Republic of China.

2. Wulin

The nickname of ancient Hangzhou was first recorded in the Han Dynasty and was named after Wulin Mountain. It is generally believed that Wulin Mountain at that time was the collective name of the mountains west of West Lake today. Song Zhou Mi is the author of Legend of Wulin.

3. Yuhang

When the Sui Dynasty established Hangzhou in 589 A.D. (Hangzhou was originally established as a state, and it was also the beginning of the name of Hangzhou), the earliest state government (the seat of the state government) was in Yuhang (now Yuhang Town, Yuhang District) and moved to Qiantang County in 590 A.D., so Yuhang was also called another name of Hangzhou. For example, Bai Juyi's "Cold Spring Pavilion": "The southeastern landscape of Yuhang County; As far as the county seat is concerned, Lingyin Temple is especially important. Next to the temple, the cold spring pavilion is one. "

4. Lin 'an

In the Southern Song Dynasty, Emperor Gaozong avoided disaster in Jiangnan and promoted Hangzhou to Lin 'an County, which was the capital of the Southern Song Dynasty. This is an ancient name of Hangzhou. Note that it is a different concept from today's Lin 'an City, Zhejiang Province. At that time, Lin 'an Prefecture was in Hangzhou today.

5. People and Qianjiang River

From Sui Dynasty to Five Dynasties, with the expansion of Hangzhou, Qianjiang County was established. In the Northern Song Dynasty, Qianjiang County was changed to Renhe County, and a city was established with Qiantang County.
