You are such a funny guy, I don't know how to prove it for a moment. I think I can prove it through my own knowledge. I don't need any so-called reward to explain the facts. I am a backend programmer, currently working on a large model project, using GraphRAG and DeepSeek to build a recommendation engine for Internet links. I am also interested in functional programming, such as lisp haskell minikanren. The salary of programmers in China is relatively high.
