Campus network is an educational network, which can access the student system and forum library of Jida University. No more than 200 yuan in a year. Open to Shaw Library. Other campuses don't know. Ask your brother and sister. The disadvantage is that some websites cannot be browsed. One thing, of course, is to choose courses, check scores and see notices, and download things quickly and conveniently.
The other is Netcom Broadband. You need to go to Unicom Hall to handle this yourself. You can choose 1M or 2M, with monthly subscription and annual subscription. I use 1M for monthly subscription and 40 yuan every month. The speed is ok. We used it all. The cat will pick it up by itself, and someone will tell you where it is. Go home on holiday and stop for a month or two. The advantage is that everything can be downloaded, and watching movies online is fast. According to my observation, watching movies on campus network is slow, but downloading speed is fast. The disadvantage is that you can't get into the campus system, and you can't even check the scores of course selection.
Of course, routers are forbidden in our school. But in private ... but being caught by the school is a demerit.
