For hotels in China, international travellers usually choose Booking, Agoda or the international Trip.com; domestic options include Trip.com, Meituan and Fliggy. Prices for the same hotel can differ by 20 percent or more between platforms - compare.
Room types: dachuang fang means one big bed, shuangchuang two twins; han shuang zao means breakfast for two included. Some hotels charge extra per guest for breakfast - confirm on arrival.
Foreign-guest policy: almost all city hotels and homestays accept foreign guests, but tiny guesthouses may not be licensed for it - check when booking or confirm by phone.
Smoking: Chinese hotels usually separate smoking and non-smoking floors, defaulting to non-smoking. Airbnb-style homestays are rarer outside first- and second-tier cities.
Check-in: bring your passport; most hotels take a deposit (credit-card pre-authorisation works). Checkout is generally noon; late checkout may cost extra.
