Campus official website: Visit official website of Shihezi University, and look for information related to the classroom or curriculum arrangement in the column of the homepage or academic affairs office. Usually, the school will announce the use arrangement and curriculum of each classroom, and through this information, we can judge which classrooms are empty.
Bulletin board at the entrance of the teaching building: usually, the classroom use arrangement or curriculum schedule of the day is posted at the entrance of the teaching building or on the bulletin board. By observing this information, you can find a free classroom.
