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 the passport validity is sufficient.

Destinations usually have well-developed public transport networks, including underground, bus and taxi services. Purchasing stored-value transport cards (e.g., Macau Bus Card, Hong Kong Octopus, Taiwan EasyCard) makes using 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), Japan uses the Yen (JPY). Major shopping centres and hotels generally accept credit cards, while markets and small shops are primarily cash-based.

Each destination 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 fundamental requirement of civilised travel. Dress conservatively at religious sites, seek permission before photographing, and avoid loud talking. In Japan, specific etiquette must be observed in restaurants and public places, such as bowing when entering temples and removing shoes indoors.
