Although “tap water” in China is theoretically safe by World Health Organization standards we do not recommend you drink it. In most modern hotels in the larger cities they operate their own “in-house” water treatment systems providing safe drinking water throughout the hotel. Other hotels provide thermos bottles of safe drinking water. Bottled mineral water is also available in your hotel mini-bar at an additional charge. In the shops or street, it is very common and cheap at about USD0.5/bottle.
