How can I open a visa or MasterCard account from China?

If you plan to open a credit card, I'm afraid that won't do, for you are required to show some certificate to prove you have the ability to pay the debt.
But if you are going to open a debit card, you can apply for it in most banks in the country. Remember to bring your passport with you.

My question is how can I open MasterCard

Honey, both MasterCard and VISA card provide two kinds of products, credit card and debit card. Since you are a student and don’t have stable income, it should be impossible for you to apply for a credit card. But you can get a debit card using your passport.
