I come from Nanjing. What are the procedures for traveling to Hong Kong and Macao? Can I use RMB? Can I use a credit card?

If the landlord's household registration is in Nanjing, go to Nanjing to apply for the Hong Kong and Macao Pass. The first time, you must go in person, you must have a household registration ID card, and you must take photos ... Then he can go to Hong Kong and Macao by land, sea and air ... If it is a honeymoon, it is usually about 10000 yuan for two people for five days ... If he spends money in Hong Kong, he will be converted into Hong Kong dollars. If you spend money in Macau, you can change it into Portuguese currency ... If you don't have enough cash, you can use UnionPay to swipe your card. Now Hong Kong and Macao support the payment of UnionPay free of charge, and there are discounts ... If Minsheng credit cards are VISA and MASTER or UnionPay, you can ... If not, you'd better use paper money ... I suggest that the landlord should choose fewer people ... and enjoy a more comfortable time ... I wish the landlord a pleasant journey! ! !
