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 your passport has sufficient validity.

Destinations usually have well-developed public transport networks, including underground/metro, buses and taxi services. Purchasing stored-value transport cards (e.g., Macau Bus Card, Hong Kong Octopus, Taiwan EasyCard) can make using public transport more convenient.

Each place uses its local legal currency. 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 Japanese Yen (JPY). Major shopping centres and hotels generally accept credit cards, while markets and small shops primarily use cash.

Each place has a rich food culture. Macau has Portuguese tarts, pork chop buns and Macanese cuisine; Hong Kong has dim sum, roast meat and fish ball noodles; Taiwan has bubble tea, xiaolongbao and night market food; Japan has sushi, ramen and tempura.

Respecting local cultural customs is a basic requirement of civilised tourism. Dress conservatively at religious sites, ask for permission before taking photographs, 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 when entering indoor spaces.
