In terms of academic attitude, Mr. Yang emphasizes that "clumsiness is better than ingenuity, and simplicity is better than brilliance". He often told us, don’t take tricks at the beginning of making things, it doesn’t matter if you are stupid, you can only talk about cleverness when you get familiar with it honestly. Want simple things, not flashy things.
Mr. Yang is like this. He has many concerns, but he doesn't necessarily do it. He often told us that when doing research, we must first take into account other fields while doing research based on our own situation. When physics has progressed to a certain level and your ability has also reached a certain level, you can turn to good problems that you think are more valuable.
Mr Yang did just that. While working on the Yang-Mills theory, he took care of others and kept accumulating. When the physical development and personal accumulation reached a certain level, he turned to the Yang-Baxter equation and its physical application.
