Most countries' visitors can enter without a visa, with specific requirements depending on passport nationality. It is recommended to check the destination's official immigration/border entry website before departure to confirm the latest regulations, and ensure the passport has sufficient validity.

Destinations typically have well-developed public transport networks, including underground, bus and taxi services. Purchasing stored-value transport cards (such as Macau Bus Card, Hong Kong Octopus, Taiwan EasyCard) can make using public transport 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), Japan uses the Japanese Yen (JPY). Major shopping centres and hotels generally accept credit cards, while markets and small shops primarily use cash.

Each region has a rich food culture. Macau has Portuguese tarts, pork chop buns and Macanese cuisine; Hong Kong has dim sum, siu mei and cart noodles; Taiwan has bubble soup, 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 photographs, and avoid speaking loudly. In Japan, specific etiquette at restaurants and public places must be observed, such as bowing at temples and removing shoes before entering indoors.
