How can I put it? The landlord is a local tyrant. Local tyrants or nouveau riche in Chinese mainland generally don't like credit cards, and find it useless to be complicated. They like cash or savings cards! Rich people in Hong Kong, Europe and America like to use credit cards, because they think it is a symbol of status, and banks will give them a lot of convenience, such as booking air tickets and inviting them to participate in the golf open! In addition, China's credit information system is gradually improving. If two people have the same conditions, but the other person has a credit card and a good credit record, then no matter what loan, the bank will be more willing to choose him! It is blank for people without credit cards to check their credit records. If they have a credit card, they will have a lot of information and it will be convenient to deal with banks in the future!
