Learning can't see the barrage.

This is because Mr. Xue Tong has the privilege of drilling wells and forbidding words, so there is no barrage. If you want to send a barrage, you can talk to the teacher and discuss it.

Barrage refers to the comment subtitles that pop up when watching videos online. Barrage has become the feature of a special player, and the barrage system is the core of the barrage player. The barrage can give the audience the illusion of "real-time interaction". Although different barrage is sent at different times, it will only appear at a specific time point in the video, so the barrage sent at the same time is basically the same theme, and when participating in comments, there will be the illusion of commenting with other viewers at the same time.
