Nan huaijin talks about immigration.

Lack of research in this field, find several typical explanations for your reference: \x0d\ Qian Mu explained \x0d\ In human nature, good and evil can be transferred, while knowledge at the upper level cannot be transferred to evil, and stupidity at the lower level cannot be transferred to good. \x0d\ Yang Bojun explained: \x0d\ Only a first-class wise man and a second-class fool can change it. \x0d\ nan huaijin's explanation: \x0d\ Only the first-rate smart people and the most stupid people are not affected by the environment. \x0d\ Li Zehou's explanation: \x0d\ Only the smartest and stupidest people will not change. \x0d\ Liu Taite: \x0d\ Only those who keep making progress can achieve intelligence and wisdom. People who have no ambition, do not work hard and are willing to lag behind will become more and more stupid. This is the eternal truth.
