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 for the latest regulations and ensure the passport has sufficient validity.

Destinations usually have well-developed public transport networks, including 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 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 malls 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, roast meat and horse noodle stalls; Taiwan has bubble milk tea, xiao long bao 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 photos, and avoid speaking loudly. In Japan, specific etiquette must be followed at restaurants and public places, such as bowing when entering temples and removing shoes indoors.
