Well, I agree that this website is often concerned because of its low cost and high benefits, but it is also a "dead order" of students, and we have to. The operating mode of this website is "closed to the outside world". Unless you are a student and the school is registered, you can't get in, so you can't surf the Internet. Network chaos occurs from time to time, and our new generation must stand up and destroy these unfair platforms! ! !
