It means more for more work, which means more for more work. "Heaven" in The Analects of Confucius means "providence", "reward" means reward and return, "diligence" means diligence and dedication, and "Heaven rewards diligence". So the general idea is: God will realize the wishes of hardworking people. If we work hard, we will gain something. As long as we make unremitting efforts, improve and enrich ourselves to the maximum extent, and do everything possible to improve our competitive strength, we will have a bright future.
