It turns out that there are Hui people in Lhasa, but it seems that neither side likes them.

There are two types of Hui people in Lhasa. One is a Muslim who lives in the world and has moved from Kashmir and the mainland in history. He speaks Tibetan, wears Tibetan clothes, marries Tibetans and has a good relationship with them. The other is the floating Muslims, who, like the Hui people in the mainland, do business and work in Lhasa, mainly with local people in Lhasa.

If you don't like it, just experience it yourself.
