The problem of theory and practice is actually the problem of quantitative change and qualitative change. I suggest that you have time to read philosophy textbooks in college. If you find it difficult to understand, you can refer to ZZ textbook for the second grade of junior high school in full-time nine-year compulsory education.

"I heard that there is specialization in the technical field". Those who study engineering should have heard of this sentence, right? ZZ textbooks of Grade Two are all some of the most basic theories. Just because you studied and passed the exam doesn't mean you really understand.

In short, while pursuing material wealth, we should reflect more on human nature and mind, and pay more attention to nature and the spiritual world while material wealth is growing at a high speed. Don't damage or deviate from human nature by losing the pursuit of material things. I hope you can use philosophical feelings to shape a philosophical life for yourself that is higher than material wealth.
