As an alternative to a hotel receipt, you can also present an invitation letter from a Chinese citizen or a foreigner with a residence permit. The letter should contain information about the applicant (such as your name, gender and date of birth), information about your stay in China (itinerary, length of stay, etc) and information about the person that is inviting you (name, telephone number, address, signature and copy of their Chinese identity card, or if the person isn’t Chinese, a copy of their passport pages containing their photo and residence permit).

Corporate, government and foreign credit cards are high risk. They have the highest interchange rates. You may ask why. Simply, if someone from a foreign country buys an item here but refuses to pay for it later, perhaps because of a dispute, it is very difficult, sometimes almost impossible to get that money back. Also, people in corporations and government make purchases that are not authorized by higher management. If they quit or are terminated, these entities will often dispute the charges as unauthorized. This makes these three card types high risk.
