I will soon move to Wuxi and will be working in Shanghai. I will catch a D or G train every day to and from work. Is it possible to buy a weekly or monthly or even quarterly ticket instead of buying a ticket every day? I know I can buy tickets up to 10 days in advance, so I guess I would always be assured of getting a ticket, but a weekly or monthly, etc, ticket in the West is much cheaper and it also gives the option of traveling on any train on a particular route or within a particular boundary. It's also far less bother than buying a ticket every day. is there such a system in China?
thanks
