Since Hong Kong and Macao are called "international metropolises", RMB, Macao dollar, Hong Kong dollar and US dollar are all in common use and can be circulated

The Hong Kong dollar is the legal tender of the Hong Kong Special Administrative Region. With the development of society, the relationship between the mainland and Hong Kong has become closer and closer in recent years, and economic exchanges have become more frequent. Many mainland tourists will travel to Hong Kong. Therefore, at present, Hong Kong people are also willing to accept RMB. Before visiting Hong Kong in the past, it is better to exchange some Hong Kong dollars, because if RMB is used directly, the cash exchange rate will not be cost-effective

According to Article 111 of the basic law of the Hong Kong Special Administrative Region of the people's Republic of China, the Hong Kong dollar is the legal tender of the Hong Kong Special Administrative Region and continues to circulate

the right to issue Hong Kong dollars belongs to the government of the Hong Kong Special Administrative Region. The issue of Hong Kong dollars requires a 100% reserve. The issue system and reserve system of Hong Kong dollars shall be prescribed by law

the government of the Hong Kong Special Administrative Region may authorize designated banks to issue or continue to issue Hong Kong dollars in accordance with its statutory authority on the condition that it knows that the issuance basis of Hong Kong dollars is sound and that the issuance arrangements are in line with the purpose of maintaining the stability of Hong Kong dollars

What souvenirs are worth buying and how much money you need to take to Hong Kong depends on the specific itinerary

< H2 > extended information:

of course, in addition to RMB cash, you can also swipe UnionPay card (the system automatically converts according to the real-time exchange rate). At present, many businesses in Hong Kong and Macao support swiping cards. As long as domestic bank cards with UnionPay logo are used, they can swipe cards in Macao. For example, in some large stores, restaurants and supermarkets, most of them don't need service charges. However, when buying digital procts to swipe UnionPay, almost all businesses have to impose 2% - 3% service charges

now there are many businesses supporting Alipay and WeChat payment. p>
