Shenzhen - Post Report Question and Answers
Are credit cards widely accepted and safe to use locally? Are ATMs common and do you recommend using them? Are they safe to use?
If you have a Chinese credit or debit card you should be okay at most places, but you may encounter issues with foreign-issued cards. And some smaller places will not take credit cards are all. ATM are plentiful, but do not assume that your foreign ATM card will always work. If you find a bank that takes your card, make a note of it. - Sep 2015
