The official currency is Chinese Yuan (CNY / ¥), also called Renminbi (RMB). Notes: ¥100, ¥50, ¥20, ¥10, ¥5, ¥1. Best exchange rates are usually at major banks (Bank of China) — avoid airport or hotel desks which charge 2–5% more. NEVER exchange money with random people on the street — this is illegal and you WILL receive counterfeit bills. Always count your change and learn to spot fake ¥100 notes.
