Improve yourself, including physical fitness and knowledge literacy. Health is a person's most important wealth, and it is the foundation and premise of having a normal life, so a high-quality life can't be without fitness. In addition to outdoor sports such as simple morning running in fun run (remember not to go alone, personal safety is also super important), you can go to the gym if you have the conditions. In fact, gyms are more common now, and the consumption is not as high as before (especially near the university town).
