Don't mislead others upstairs. There is only one doctoral program in ethnology in South-Central University for Nationalities. Where did the national key discipline of organic chemistry come from? South-Central University for Nationalities has only three major construction sites with national characteristics and no national key disciplines. Yangzhou University has seven postdoctoral mobile stations, one of which is a chemistry postdoctoral mobile station. Yangzhou chemistry postdoctoral mobile station relies on the Institute of Chemical Engineering, supported by doctoral programs in physical chemistry and analytical chemistry, and physical chemistry is the national key discipline training point. Main research interests: colloid and interface chemistry, electrochemistry and biosensor, physical chemistry of materials, nanotechnology, etc. President Yang Da is engaged in chemistry, as if he were the president of the National Colloidal Chemistry Society. Therefore, it is naturally clear which is better or worse. Yangzhou University is far stronger than Central South University in terms of location advantage, strength and ranking.
