At present, China Merchants Bank in Zhengzhou has not come to the door to handle credit card business, so you'd better take the time to fill out the form yourself and bring all kinds of materials together, including the original ID card and financial proof (such as real estate license plus income certificate, vehicle production certificate, bachelor's degree certificate plus income certificate, unit social security and China Merchants Bank savings card, only one of the five conditions can be met). Filling out the form is still relatively fast.
