First, I also watched pirated videos in the postgraduate entrance examination, but the books are all genuine, so I can't support piracy, but I can't oppose piracy, because it's not as simple as I thought. You said you should listen to math, politics and English in class? You see, Zhang Yu is not bad at math. Do you still want to take classes in New Oriental? Teacher Li Yongle is the most modern, so do you want to stop buying online courses in Li Yongle? This is also a place where students can't choose. Different teachers have different advantages. If you want to buy it all, how much will it cost, so it is not unusual to have piracy. But some students still pay for genuine products. This is support for practitioners and respect for intellectual property rights.

Second, students who have watched the video know that the video will be removed because of infringement, resulting in the video watched today will be gone tomorrow, so students who buy genuine ones don't have to worry about this situation.

Third, some people spend money to buy time, while others spend time to make money. Students with family conditions allow them to spend money to buy genuine copies, which saves the time to find resources, while students looking for resources have to spend time switching various video software in order to find a complete video. Therefore, when the time for postgraduate entrance examination is so precious, it is also a time-saving method to spend money on videos.

Fourth, the online courses bought are very timely, especially politics. The teachers revised it slightly according to their previous experience. Generally, the newly-launched courses are uploaded to the shelves soon, so I watched more pirated videos in previous years.

Fifth, I hope to support the original version as much as possible, because you don't want your master's and doctoral thesis to be copied by others, and there is nothing to do. Is it a little late to call for the protection of intellectual property rights?
