Cash & credit card use in Shanghai

Soon to be arriving in Shanghai, for a 6 month or more trip.

So, to my question, about getting cash, paying in bars, bank machines, ATM´s.

Not sure how long I will be there yet, minimum 6 months.

With only foreign bank card, can you please confirm for me that there are plenty of ATM´s everywhere? and they give you a choice of languages?

Any more info detailed, do ATMs accept ´Maestro´ cards? or only master card and Visa?

I read that some do, any idea if most do? or only a rare few? I will of course also ask in my bank here. (CZ)

Thanks.
