No matter where you are, it takes courage to choose to study for a doctorate. Regardless of whether graduation is easy or not, from the perspective of employment alone, it is not as easy for a doctor to find a job as before. Although the materials in Gong Kun are not bad, there are many cattle schools and people at home and abroad, so it is not easy to get into a decent university or research institute after graduation. Therefore, you must think carefully about reading a PhD, but if you really have a strong interest in scientific research and consciously have a certain talent, you still support it! After all, all roads lead to Rome!
