Credit card mainly depends on the details of the card, such as annual fee, points, etc. I think the bigger the bank, the better. China Merchants Bank is very popular in Shenyang. Personally, they have a lot of business in Shenyang, and the cards are varied. Personally, CCB and ABC are good. You can compare them in official website of several banks. ICBC, CCB, ABC, China Merchants Bank and transportation mainly depend on the details of credit cards, regardless of what they write.
