I can tell you responsibly that it doesn't matter. The physical examination of graduate students in Shanghai is very formal. The physical examination officer said that unless there is a serious heart disease that affects the class, they will check the general diseases, but in fact they ignored them. Moreover, activities such as hepatitis B and Xiaosanyang are not affected by state regulations, so it doesn't matter at all. It is more important for you to pay attention to the exam results.
