Since more and more tourists are going to Tibet, more and more Tibetan people get used of seeing the "Big Noses" (western people) with jeans, sun glasses and some of them with shorts (It is prohibited to wear shorts among the Tibetans), the above rules are not obeyed so strictly as before. But we still suggest you take the above advice and travel to behave well.
