I have concerned Chinese agriculture because I have concerned Chinese food, which has not solved up to now but more and more hard solve. The reason for it not only because of shortage of farmland and big population in China, but more and more important, Chinese scientists, especially our agricultural scientists, who don't accepted that my academic ideas instead their academic ideas. If someone research our national agriculture in with Theory of Soil, it is a litter matter that our degree of self-sufficiency in grain will reach over 100%. If you don't believe that is true, please you read my《Theory of Soil》.
