Jiangsu primary school mathematics is a Soviet version, and Chinese is a ministerial version. In the second grade of primary school, mathematics is the Soviet version, and Chinese is currently compiled by the unified Ministry. As far as I know, at present, all primary and secondary schools in Jiangsu are Jiangsu version of mathematics, which is compiled by Chinese Department. There is little difference between the Jiangsu Education Edition and the People's Education Edition, only the order is different, but the extracurricular exercises of the Jiangsu Education Edition are more difficult than the People's Education Edition.
