I'm glad to contact you through the screen. I am very grateful to all parents for taking the time to attend this online parent-teacher conference with their children. At the beginning of the meeting, I want to emphasize to you once again that although the epidemic has been buffered, we still can't relax our vigilance. We should always keep a vigilant heart, and don't let things drift because the situation improves. Children should remember to wash their hands frequently, and don't touch their nose, mouth and eyes with their hands. Only in this way can we get together with you on campus faster!
