Click the "Nail" icon and select the class group you want to enter. Find "Online Classroom" at the bottom. I entered the online classroom page. This page is divided into two parts. 1. The top column of the page is the mobile phone notification column of the tutor. The leftmost clock can remind the teacher to grasp the class time. 2. The left side of the next page has the largest area, which is equivalent to a blackboard. 3. The rightmost part of the page: The instructor's camera content appears at the top.

The disadvantage of mobile phone online class is that you can't use courseware. Chinese, English, history and other subjects that use more courseware need to be operated on the computer.
