As a graduate student of 14, I give you a very good way to download videos. I hope you can adopt it after watching it.

All the videos on the website can be downloaded, and the information inside is available. Sign it for a few days and you can download all kinds of materials for free, including postgraduate entrance examination, national examination, college entrance examination and so on. That's how I got here.

It should be 14 years later or now.
