tibetans and mongolian drink tea with yak milk or cream and salt and other things because that when they began drinking tea many many many centuries ago adding things to tea was a custom in all china. an because tea traded to them was of very poor quality. because they dont have vegetable or fruit good supply, they need tea very strong. poor quality brew very strong not good taste. so they add many things to it to make it taste better.
there are very good assam tea and ceylon tea that are sweet taste, no need sugar. most people think only low quality tea made in assam or ceylon. this is not true.
many my customers from uk not drink tea with milk or sugar. good tea no need sugar they say.
