If you want to revitalize the country, you must first make a career and create your own world. As the saying goes, "How can you see a rainbow without experiencing wind and rain?" If you just want to have fun and don't make progress, you will definitely make yourself a loser and be remembered for thousands of years. "Worry can rejuvenate the country, and leisure can die". This sentence was said by Ouyang Xiu, a great writer in the Song Dynasty, when summing up the reasons why the Tangzhuang School won the world and then lost it. The author points out that Tang's success is due to his efforts and anger, while his failure is due to his pride and happiness. It can be seen how important it is for a person, even a country, to worry about work and relax.
