Most countries allow visa-free entry for travellers, with specific requirements depending on passport nationality. It is recommended to check the destination's official immigration/entrance 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/metro, bus and taxi services. Purchasing stored-value transport cards (such as Macau Bus Card, Hong Kong Octopus, Taiwan EasyCard) makes 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), and Japan uses the 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 egg tarts, pork chop buns and Macanese cuisine; Hong Kong has dim sum, char siu and cart noodles; Taiwan has bubble tea, xiao long bao and night market delicacies; Japan has sushi, ramen and tempura.

Respecting local cultural customs is essential for civilised travel. Dress conservatively at religious sites, ask permission before taking photographs, and avoid loud speaking. In Japan, specific restaurant and public place etiquette must be observed, such as bowing when entering temples and removing shoes indoors.
