Brief introduction of wanling

Wanling is Xuancheng, with an ancient name. In the Three Kingdoms, it was also called Danyang and Wanling, with Jiangsu and Zhejiang in the east and Shanghai and Hangzhou in the land. It is the southeast gateway of Anhui. With pleasant scenery and a long history, it has rich historical and cultural connotations. Wanling has experienced several major disasters in history: Xuancheng was depressed by the war at the end of Yuan Dynasty, and the craftsmen in Xu Anbi avoided the nearby lake pen, which brought the rise of lake pen; During the Taiping Heavenly Kingdom, the repeated tug-of-war between the Qing army and the Taiping Army led to a sharp drop in population (for example, the population of Xuanzhou dropped from 165438+ 10,000 to 250,000, and the population of Guangde dropped from 300,000 to 5,000, resulting in a large number of immigrants from Hubei, Henan and Jiangbei in Xuanzhou, Guangde, langxi and Ningguo). The Mei surname of Wanling has the reputation of "Plum blossoms bloom everywhere in Xuancheng". Since the Song Dynasty, Mei Dingzuo, Mei, Mei Guangdi and other celebrities have emerged. Among them, the famous mathematician Mei Wending made great contributions to China's mathematics and was appreciated by Qianlong. He combined his previous math books into a book.
