We have to break with traditional ideas that land resources are limited, and we have to set up new ideas that land resources are not limited. Because no ways can solve Chinese food completely including GM seeds, change medium-lower output field, international cooperation and land purchased abroad and so on except increase of land resources. Due to fetter by traditional ideas, Chinese scientists can not throw away them and accept my academic ideas, same as land resources are not limited. I think that as a scientist, you would be a person, who want to seek truth and change ideas from the old into the new, so to change ideas are good things, because you have sought truth just as like Laozi said a man with high innate quality hears the truth and carry out it often. Confucian says that when you hear someone shows your shortness and then you would be glad.
