give yourself an output

       It has been nearly five years since graduating from university. After graduation, I have been engaged in my major. I am lucky. The only bad thing is that I have not achieved any good results, and I am still a bottom-level coder. The career planning goal at graduation is technical manager, which seems to be much worse. Maybe it's time to export what I've learned. I used to do it intermittently. Now I want to export what I know and know, as an explanation for my five years.
