Internet and VPN (The Great Firewall): Many Western websites and apps (Google, Facebook, Instagram, WhatsApp, X) are blocked. To access them, it is essential to install a VPN (Virtual Private Network) on your phone and computer *before* arriving in China.

Payments and Money: The currency is the Yuan (CNY or RMB). Although credit cards are accepted in large hotels and restaurants, China is an increasingly mobile payment-oriented society (WeChat Pay, Alipay). Cash is useful for small businesses and rural areas, but mobile payments dominate daily life.

Visa: Most travelers require a visa to enter China, which must be obtained in advance from a Chinese embassy or consulate. However, there are short-stay visa waiver policies for certain nationalities, so it's crucial to check the specific requirements for your passport before you travel.

Public Toilets: Public toilets are plentiful, but they are often 'squat toilets' and do not usually have toilet paper. It is highly recommended to always carry a roll of paper or tissues with you.
