On the first week of new semester, our school provided 14 professional classes for international students majoring in International Business. Currently, there are around 80 students totally for this major. About 20 students are on campus, and the rest are out of China due to epidemic situation. In order to maintain the quality of teaching, all of course teachers utilize live broadcast to teach by Tencent meeting, so teachers and students can communicate smoothly. With the consideration of students with internet problems, our teachers copy the videos when having classes. After the class, they will share videos with students who have internet problems. With the effort of teachers and students, on-line teaching was held successfully on the first week.
