Does anyone know whether Guangyuan, Sichuan is a southern or northern city?

I feel dizzy, the geography above is not good enough!

1. The dividing line between north and south in our country is the Qinling Mountains and the Huaihe River. Guangyuan is south of the Qinling Mountains. In this regard, Guangyuan belongs to the south.

2. Sichuan belongs to the south of China, and Guangyuan belongs to Sichuan, which also shows that Guangyuan is from the south.

3. Cantonese belongs to the southern language family, and Guangyuan is from the south.

4. Even in terms of China's territory, Xi'an is the center of China's territory (the geodetic coordinate point is in Xi'an), and Guangyuan is hundreds of kilometers south of Xi'an, and Guangyuan belongs to the south.

5. Guangyuan’s rainfall characteristics are those of southern cities.

6. The Jialing River flowing through Guangyuan belongs to the Yangtze River water system, which should be the southern water system.

There are many reasons. In short, we cannot divide north and south like you do, and we have to look for reference objects. Mathematics is too much. Does it mean that if Hong Kong uses the South China Sea as a reference, it is still a city in northern China? Funny!
