Abstract: During the COVID-19 epidemic in 2020, the new term of universities across the whole country was postponed. Under the guidance of the Ministry of Education, the colleges decided to adopt the online teaching mode. Online teaching has the advantages of innovating teaching experience, enriching teaching resources and cultivating students' independent learning ability. However, it also faces the challenges brought by network technology, teacher-student relationship and teaching design. In this situation, the educational subjects from all sectors of society should unite together and think actively about the corresponding countermeasures to ensure the smooth implementation of online teaching.

Key words: Online teaching, University, Advantage, Challenge, Countermeasure
