Tibetans have the custom of presenting milk tea, butter tea and highland barley wine to guests. When a guest comes to a Tibetan home, the host will toast three glasses of highland barley wine. No matter whether the guest can drink or not, he must dip his ring finger in the wine and flick it. If the guests don't drink or play, the host will immediately hold the wine and sing and dance to persuade them. If the guest has a small capacity for alcohol, he can take a sip and ask for more wine. After two sips of wine, the host fills up the glass and the guest drank it all in one gulp. In this way, the guests don't drink much, and the host is also very satisfied. According to Tibetan customs, when the host presents buttered tea, the guests cannot refuse, and they must drink at least 3 bowls. The more they drink, the more popular they are.

    The etiquette of offering buttered tea is: the guest sits at a Tibetan-style square table, the hostess puts a small wooden bowl inlaid with silver in front of the guest, and then pours a bowl full of buttered tea for the guest with a pot or thermos, and the host and guest start chatting; When the host lifts the pot again, the guests can pick up the bowl, blow gently into the bowl, and then take a sip and say something praising the well-made tea; when the hostess lifts the pot for the third time, the guests sip Take a second sip of wine; guests are ready to leave, so they can drink a few more sips, but not dry, and there must be some tea bottom with butterflies floating in the bottom of the bowl.

Tibetans are most taboo about other people touching sacred objects such as Buddha statues, scriptures, beads and amulets.
