Visitors from most countries can enter without a visa; specific requirements depend on passport nationality. It is recommended to check the destination's official immigration/entry website before departure to confirm the latest regulations, and ensure passport validity is sufficient.

The destination usually has a well-developed public transportation network, including metro, bus and taxi services. Purchasing stored-value transportation cards (such as Macau Bus Card, Hong Kong Octopus, Taiwan EasyCard) can make it convenient to use public transportation.

Each place uses local legal tender. 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 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 tea, xiaolongbao and night market delicacies; Japan has sushi, ramen and tempura.

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