Qinghai's climate in winter is harsh. Vast parts of the province are high, treeless steppe. Don't go off the beaten track on your own. Bring warm clothes and extra food supplies. It can snow year-round, and even in July temperatures regularly dip below freezing at night in regions above 4000m. Winters are brutally cold in much of Qinghai with temperatures at night between -20C and -30C.
Sunlight
is intense here. The province receives very little rain, so those cloudless days and lack of shade mean it's very easy to get burned here. Bring plenty of sunblock. A hat is also a good idea.When trekking through nomadic areas be careful around the dogs. Tibetan dogs in Qinghai are used as guard dogs and will attack anyone they are unfamiliar with. These dogs are quite large and often can weigh 60 kg or more.
Altitude sickness is a reality in Qinghai with much of the province being over 3000m. Give yourself plenty of time to acclimatize before going to high altitude regions. Try to ascend as slowly as possible.
talk
While most inhabitants understand and speak Mandarin, Tibetans take pride in their culture and often prefer to speak Tibetan. Any effort you can make will be appreciated.
Local Han speak a regional variant of Chinese called Qinghaihua. The province's many ethnic groups all have their own languages, including Dongxiang, Mongolian, Salar, Tibetan and Tu. At any travel agency, big restaurant or hotel, standard Mandarin works fine.
The Amdo Tibetan dialect is spoken widely by Tibetans in the prefectures of northern and eastern Qinghai, while Kham Tibetan is spoken by Tibetans in Yushu prefecture in southern Qinghai.
