I put The Classic of the Virtue of Tao and Theory of Soil,same as Three Series of Literatures of Artificial Soil Technology,at the same level. The former with about 5000 words had written by Li Er 2500 years ago, the latter with about 50000 words have written by Li Pengfei. The former says a method understanding the world, but the latter says a method solving the problems. It is known that the methods to understand the world maybe have several ways, but sometimes the best method is unique, so this is why named Laozi's philosophical ideas have not been to become social mainstream over several thousands years, but nicknamed Xaozi's academic ideas will become social mainstream sooner or later and it will be accepted by the society.
