Recently, the policy cracked down on off-campus training, and the live class also belongs to off-campus training, so there is no way to watch it for the time being.

There are roughly two kinds of live broadcasts. One is to provide TV signals to watch on the Internet, such as live broadcasts of various sports competitions and cultural activities. The principle of this live broadcast is to convert TV (analog) signals into digital signals and upload them to the website for real-time viewing, which is equivalent to "network TV"; The other is what people know as "webcasting".
