Which province does the sun belong to?

The sun is not a city, and there is no city or county called the sun. The sun may be the name of a company, and many companies have the sun in front of their names.

I don't know if you are looking for Sun Town. There is a Sun Town in Zhejiang Province, which belongs to Lin 'an District, Hangzhou City, Zhejiang Province. It is located in the middle of Lin 'an District, bordering Qianzhen in the east, Qianchuan Town in the south, Heqiao Town and Changhua Town in the west, and Yuntishe Township in Ningguo City, Anhui Province in the north.
