Pan is my student, and he's also a Huaxia person. I'm quite satisfied with him. I'm saying this simply because there aren't many Huaxia people researching this issue, so this kid largely relies on self-study. What if he were Schulz's student?
This is really discouraging. Sixteen years of effort, and yet a self-taught kid can easily spot flaws in the proof process. I believe you might feel what I feel now, as if the problem was actually simple, but I'm too incompetent, making it seem so difficult...
Danis kept on jabbering, and nagging is originally a way to vent emotions, and this method is quite civilized.
At least there was no foul language.
However, Danis clearly didn't notice that his negative emotions were spreading outward along with his nagging.
The two collaborators listening to his nagging meant that these negative emotions doubled in the transfer process.
Happiness can be transmitted, but doubling it is difficult, while doubling this negative emotion is quite simple.
