How much is the air humidifier? Cheaper ones. Is it sold in Tibet? Where is it?
It is available at Yutu Road (Pedestrian Street) in Lhasa, Tibet, and the price ranges from 100 to 400 yuan. It's best not to buy tens of dollars on the cheap, because it's too noisy and easy to affect sleep. If you have the habit of online shopping, you can buy a cheaper humidifier with good quality in JD.COM Mall (relative to the price in Tibet).
