(In my opinion, the video number is more like a tool. What a tool can do depends entirely on how each of us uses it. Used well, it will naturally have good results. If you don't use it well, you should learn how to use it. very useful. Whether you are selling live broadcasts or attracting traffic, there are huge opportunities here, so my suggestion is to study hard when you have time, even if you fail, you can learn from experience, and if you succeed, you will make a difference and accumulate more.)
