Is the tap water drinkable in Sanya?
Tap water is not drinkable in China except in some of the hotels, but it is safe for brushing teeth. All hotels supply guests in the room with a thermos of hot boiled water to make tea or coffee. Bottled water is recommended. Some hotels provide complimentary bottled water. If not, it can be purchased for about RMB2 per bottle everywhere outside the hotel.
