Essential emoticons for online class teachers

I would like to share with you a set of essential emoticons for online course teachers.Because of the epidemic, students all over the country are still taking online classes. Although they are taking online classes, homework still needs to be handed in. A "cold" sentence of handing in homework may make people reluctant, but with this set of emoticons, it will be much better, the atmosphere suddenly became more lively, and the sense of distance became less.
