At the beginning of this year, when I was a senior and a freshman, I got an annual card, 150 yuan, which can be used for 20 times ~ it was supposed to be once in 20 yuan at that time, so it was much cheaper ~ I had to use my student ID card when I did it, but I didn't need real-name registration system ~ I often lent my card to my classmates, and they could use their own student ID card to enter ~ but I had to check my student ID card every time I went in ~ It was valid for one year.
