Most countries' travellers can enter visa-free, 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 passport validity is sufficient.

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 local legal tender. Macau uses Macau Pataca (MOP), Hong Kong uses Hong Kong Dollar (HKD), Taiwan uses New Taiwan Dollar (NTD), Japan uses Japanese Yen (JPY). Major shopping centres and hotels generally accept credit cards, while markets and small shops mainly 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, roasted meats 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 photographing, and avoid speaking loudly. In Japan, specific etiquette must be observed at restaurants and public places, such as bowing when entering temples and removing shoes indoors.
