Summer vacation is from the end of June to the end of August or early September.

The last two weeks of the semester are exam week, and there is a mid-term exam.

Graduate students with full scholarships usually take vacations according to the boss's laboratory project progress, and there is basically no vacation.

Because those who get government scholarships count their working hours and have few holidays. But if the boss is good, it's no problem to give you a month, and you can also reimburse the round-trip air ticket. Of course, this is also a black-box operation or the boss will find a way for you privately.
