Most countries' travelers can enter without a visa; specific requirements depend on passport nationality. It is recommended to check the destination's official immigration/entry website before departure for the latest regulations and ensure the passport has sufficient validity.

Destinations typically 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 facilitate using public transportation.

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

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

Respecting local cultural customs is a basic requirement for civilized travel. Dress conservatively at religious sites, ask for permission before taking photos, 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.
