The abbreviation "Wan" for Anhui Province comes from the ancient Anhui state. Compared with Huizhou Prefecture, Wan Kingdom has a longer history. Wan Kingdom appeared before the Spring and Autumn Period. It is mainly located in Qianshan County and some surrounding areas. Its capital is Qianshan County today. The road leading to Qianshan Railway Station is still called Wanguo Road. At the same time, Tianzhu Mountain in Qianshan County was called Wanshan Mountain in ancient times, and now there is also Wanhe River. The Wanhe River is composed of three major tributaries: Wanshui River, Dianhe River and Changhe River. Generally, the Changhe River is the main source. Of course, this is not the most critical thing. After Anhui Province was established, the provincial capital has been in Anqing for a long time. Regardless of whether it is the ancient Wan Kingdom, Wanhe River, Wanshan Mountain, etc., they are basically all located in the Anqing area.
