Is it not possible to do research, but teaching and educating people should be fine, right? Moreover, isn't Senior Brother Chen so honest? Honest people are diligent in teaching. Besides, good universities don't just need research talents now, good teaching can still earn you respect, right?
With your respect, even if he doesn't have great achievements in research, he can still find a firm footing. Without too much research pressure, he can quickly showcase his talent in his areas of expertise, and in a few years, produce a batch of excellent students, gaining everyone's praise!
Like how I was able to publish in Ann. Math at such a young age, wasn't it because you were great at teaching? In the future, I will inherit your mantle in research, and Senior Brother Chen will inherit your mantle in education. Combined, wouldn't that be something amazing?"
