We are used to use Commute Card to take bus and subway etc. And it is really cheap, because the government gives us 60% discount. However, there still have a problem, about the card. We have to put away 20 RMB to government to take this card. And the problem is that the card is not so reliable. We got this card about 3 years ago. But the card suddenly became unavailable serval days before. And according to the government policy. I have to go to the Bus Station Center to unregister my card, and meantime get the remain of the card. But I have heard that the process is very complicated and miserable. I got here about 12 O’clock, and it was about 3 PM when I achieved my target. It was really a miserable experience. So take care of your card if you don’t take a so miserable experience like me.
