In my opinion, only when the number of people reaches a certain scale can the value of the system and system be fully reflected. Since institutions and systems must act on people, we must first own people. So, if there are no talents and experts in the company, how can we talk about training and even knowledge management? This is all floating clouds. This is why so many enterprises only have ideas without practice, and the brain drain is getting higher and higher, but no one has ever solved the root of this problem.
