Hello, what's the difference between Chinese salt and northern salt? The difference between Zhongyan and Beiyan lies in the different teachers. Beiyanzhong is the north campus of yancheng middle school, Jiangsu Province. It is the first batch of key middle schools, the first batch of four-star high schools and the first batch of national demonstration ordinary high schools in Jiangsu Province. Known as one of the "five golden flowers" of ordinary middle schools in the province, it has a strong faculty. China Tobacco Middle School is another branch school in yancheng middle school, Jiangsu Province. The teaching quality is unstable, and students can't get excellent grades. Yancheng middle school is mainly divided into four campuses: North Yanzhong (Yulong Road), Zhongyanzhong (Luming Literature Road), Kangju Road Campus and Xuehai Road Campus.
