Twenty-two years old is generally the age to graduate from college. Under normal circumstances, 18 years old is admitted to the university, and senior three studies for four years. It is estimated that many people with average grades can also be admitted to first-class universities such as Fudan University and Nanda University in Tsinghua.

At the age of 22, it's no problem to take the undergraduate course in Tsinghua, but in the future, employment and postgraduate entrance examination may be questioned and discriminated because of being too old, so psychological preparation is needed. After all, the employer doesn't want to have a senior undergraduate with a nominal age of 27, even if he is from Tsinghua;

If Tsinghua is compared to a goal, some people reach the goal quickly, and some people have limited ability to climb and roll to the finish line; People who walk fast will still walk faster in the future; Walk slowly, what others can achieve in a year will take him a long time to achieve, that's all, but this spirit is worth appreciating.
