Before 7 am, students already start their studies in the corridor. As the outdoor temperatures decreased below 0 Celsius, students had to wear heavy overcoats to keep warm. They buried themselves in piles of reference books, studying for more than 12 hours every day.

Only 30 days countdown to the national postgraduate entrance examination, students review their lessons carefully in the library. The exam will be held on Dec. 23 and Dec. 24.

College students make careful preparation for the upcoming postgraduate entrance exam.
