He entered school in September 2020 and graduated in 2024 four years later. As we know, the study time of undergraduates enrolled in full-time colleges and universities in China is generally four years. Those who take the college entrance examination and are admitted generally report for admission in September of that year and start their university study and life. After four years, when their study time expires and they pass the corresponding examinations, they can issue graduation certificates and formally graduate. It can be seen that college students who entered school in September 2020 graduated in 2024 four years later, usually in June and July of that year.
