Su Xuefeng's NLP course is not a complete psychology in essence, but the presentation of his application effect in NLP. Combined with my own business experience, I use NLP as a tool to summarize a set of application methods, which belong to practical application rather than simple curriculum research. If you are engaged in academic research, the effect will not be ideal, because the criteria for judging are different. But if you want to use NLP to solve problems in your work and life, this course is of great practical significance. NLP is a kind of psychology that originated in 1970s. Translating NLP into Chinese is called "neural language programming". These three English letters mean: N-neuro, L-language and P-programming.
