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, 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 the local legal currency. 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 malls 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, siu mei and cart noodles; Taiwan has bubble milk tea, xiaolongbao and night market food; Japan has sushi, ramen and tempura.

Respecting local cultural customs is a basic requirement for civilised travel. Dress conservatively at religious sites, ask for permission before taking photos, and avoid loud speaking. In Japan, specific etiquette must be observed at restaurants and public places, such as bowing at temples and removing shoes when entering indoors.
