All you have to do is take your computer to school. There is a video of Dongda University on the campus network. After going in, you can watch movies and watch TV there without spending any traffic.

Netcom's download is not very fast, generally 100 k/s, the campus network is very fast, and the download can be several hundred k, you can try it.

It is said that freshmen who apply for campus network will give you a six-dimensional space number in the computer center, which is almost what you call ipv6. Things can be downloaded quickly and uploaded generally, but that's all I've heard of. I didn't give it to me when I applied for the job, and I don't want it.
