Most countries can enter visa-free, but specific requirements depend on passport nationality. It is recommended to check the destination's official immigration/border control website before departure for the latest regulations, and ensure the passport has sufficient validity.

Destinations usually have well-developed public transportation networks, including metro, bus, and taxi services. Purchasing stored-value transportation cards (such as Macau Bus Card, Hong Kong Octopus, Taiwan EasyCard) can make using public transport more convenient.

Each place uses its local legal currency. Macau uses the Macau Pataca (MOP), Hong Kong uses the Hong Kong Dollar (HKD), Taiwan uses the New Taiwan Dollar (NTD), and Japan uses the Japanese Yen (JPY). Major shopping malls and hotels generally accept credit cards, while markets and small shops primarily use cash.

Each destination has a rich food culture. Macau has Portuguese egg tarts, pork chop buns, and Macanese cuisine; Hong Kong has dim sum, roast meat, and cart noodles; Taiwan has bubble tea, xiaolongbao, and night market delicacies; Japan has sushi, ramen, and tempura.

Respecting local cultural customs is a basic requirement for civilised travel. Dress conservatively at religious sites, ask for permission before taking photos, and avoid speaking loudly. In Japan, specific etiquette must be followed in restaurants and public places, such as bowing at temples and removing shoes when entering indoors.
