The tap water is not suitable for drinking. Potable water may be provided at a
few of the best hotels, so do not drink it before you ask to make sure. Boiled
water is sometimes offered in thermos bottles in hotel rooms but you also need
to make clear whether it is fresh.
Bottled mineral water is sold for around 3 RMB, and is widely available in stores,
restaurants and street kiosks. Usually, a bottle or two is provided free in your
room by the hotel.
