One of the significance of live viewing of historical review is that in this live room, some contents broadcast in the past time period have been recorded and stored, and then if you want to view historical review, you can directly click this button to view some related historical reviews.

In other words, some of the contents that were broadcast live in this studio in the past can be reviewed again, and some important contents will be selected for playback in the historical review. This is the same as the historical review in football games or other types of games, such as basketball games.

That is to say, in the live broadcast of the past period of time, some important contents can be reviewed historically, so the live broadcast dynamic viewing historical review is such a meaning.
