In the long history of more than 3,000 years in Chengdu, Huayang has always been a name closely related to Chengdu. Chengdu and Huayang are almost the most typical "Twin Cities" in ancient times, even older than Chang 'an and Wannian in Tang Dynasty.
But the origin of the ancient name "Huayang" does not refer to Huayang in Chengdu in principle. Perhaps many people know that there is an ancient book "Huayang Guozhi", the contents of which are also related to the land of Bashu.
According to the respective origins of Huayang Guozhi and Chengdu Huayang, we can actually understand that Huayang Guozhi was written by Chang Qu, an ancient scholar living in Sichuan, which contains ancient historical works about Sichuan Bashu.
However, "Huayang" in the title of the book has a specific ancient geographical meaning. Not a specific place, but a large area, covering Sichuan, Yunnan and Guizhou. It is not only a description of the history of Chengdu. This difference is very important.
The pages of Huayang Guozhi, and Huayang in Chengdu did not appear in the name of Huayang at first in history, but was established separately from the prosperous Chengdu and Shuangliu after the Tang Dynasty. It was named Huayang as a microcosm and commemoration of the ancient Huayang area, and the original origin of Huayang in Chengdu has nothing to do with the ancient book Huayang Guozhi.
In particular, chenghua district in Chengdu appeared relatively late, and it was also a new urban area divided by adjustment. The combination of the names of Chengdu and Huayang is indeed a microcosm and commemoration of the thousand-year history of Huayang County and Chengdu. It is based on the geographical origin of the two places and has no direct relationship with the book Huayang National Records.
The famous and historical value of Huayang National Records is the more grand historical geography and tribal folk customs in Southwest China. It is a big "Huayang" in the paleogeographic background. This is a traditional concept of natural geography known to the ancients, and there is no such administrative level color as county, county and state. Chengdu, on the other hand, naturally belongs to a city in the ancient "Huayang" category.
Later, Huayang was an administrative county under the county system, but it belonged to a county that was almost equal to Chengdu, or later belonged to a town under the jurisdiction of Chengdu, which was far from the "Huayang" represented by Huayang's national governance.
