Network teaching mode, there is no way to escape the status quo of one-to-many, because we are still in the stage of exam-oriented education, and many parents can't afford the high one-to-one tuition, so one-to-many is an inevitable phenomenon. So one-to-many interaction is very difficult. In fact, students' audio can be transmitted to teachers and other students who attend classes as usual, and our internet speed is not good. Once this effect occurs, the network environment will inevitably collapse.

Then there is the issue of cost. Labor costs are high. Young teachers have little teaching experience and can't be active in empty rooms and machines, especially without students' feedback. And if you hire a famous teacher, what is the cost? Including venue and labor, how many video courses will it take to get it back? So it's not worthwhile.

Not to mention the market, but to give you a computer for your research? Can you believe it? Which child gets a computer and the first thing he does is study? I am flying with the game!

Therefore, online video education has a bright future, but it is more of a dilemma.
