Mongolians are hospitable. When you are invited to a ger, enjoy it but donot forget some basic dos and donts.
Drive slowly when you are near a ger. Donot scare the cattle. Enter the ger from the left. Donot have to take off your shoes in the ger.Do not go through the herds since the owner would feel offended. Receive milk tea or wine with both your hands or right hand to show your respect.
There is no toilet but you can go to the south to the ger. The east or west to the ger is where sheep pen is while the smell may be blown into the ger from the north. The ice in the north or west to the ger is for edible water. So never pollute them.

Li Tang, the highest city in the world, lies in Ganzi Tibet Perfecture, Sichuan Province.
