Affected by the epidemic, most schools can't start school normally, because normal school may have started for about a week, but now they are all at home. For younger children, parents should communicate with teachers, because children may not be able to handle these things themselves, so they choose Ding Dingqun or WeChat group.

Ding Dingqun is not a particularly good choice, at least for parents in primary schools. Because of the influence of the environment, this software suddenly became popular, but many people may not have been exposed to it before. Ding Dingqun used to punch in and out of work as an enterprise, and then the internal communication software was not online teaching software, so many people didn't understand how its specific functions were done, how to add class groups, and how to send messages and videos.

The group chat on WeChat is the easiest to establish and the best to do, because the group chat on WeChat can contact parents by adding their own mobile phone number, so that parents can actively add WeChat, but Tintin is not so simple, because not all parents can understand what Tintin is, so WeChat is a method with the lowest cost and the highest communication efficiency. Now almost everyone will use WeChat to send messages and videos, and then conduct daily communication. There is no need to download the software separately, which will not cause greater burden to parents.

At present, quite a few schools have started online teaching. After online teaching, some problems of the platform were also found. For example, Tintin's live broadcast may be smoother and the picture quality is good. However, through the official WeChat account of WeChat, there has been a big card phenomenon. It is feasible to use other live broadcast software, but there are some technical problems that require parents and teachers to strengthen communication. After all, it is not as convenient as face-to-face teaching.
