Most countries' travellers can enter visa-free, with specific requirements depending on passport nationality. It is recommended to check the destination's official immigration/entry website before departure to confirm the latest regulations, and ensure the passport has sufficient validity.

Destinations usually have well-developed public transport networks, including underground, buses and taxi services. Purchasing stored-value transport cards (such as Macau Bus Card, Hong Kong Octopus, Taiwan EasyCard) can make travelling on public transport convenient.

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

Each place has 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 tea, xiaolongbao and night market delicacies; Japan has sushi, ramen and tempura.

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