Jiangnan's grain processing ranks first in the country (because of Yao Huiyuan), Nannong's livestock products rank first in the country (because of Zhou), Jiangsu University's computer detection of grain quality is very strong (but the specific people can't say it, all of them are average), and Nancai's grain and oil inspection is leading the country (but its technical content is limited, only because it relies on the background of the Grain Bureau), and its characteristics are not clear. In addition, Jiangnan seems to be the leader of China.
