Most countries' travellers can enter without a visa, 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 validity is sufficient.

Destinations usually 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 travelling on public transport convenient.

Each place uses the 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 place has a rich food culture. Macau has Portuguese egg 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 travel. Dress conservatively at religious sites, seek permission before taking photographs, and avoid speaking loudly. In Japan, specific etiquette must be observed at restaurants and public places, such as bowing at temples and removing shoes when entering indoor spaces.
