Stick your tongue out.
You read that right, in Tibet, it’s perfectly acceptable to stick your tongue out at someone when greeting them. The tradition started with a group of monks who would stick their tongues out as a way of showing they came in peace. Why? Because folks were afraid the monks might be reincarnations of a particularly cruel king who was known to have a black tongue. No block tongue, no evil king. The greeting just happened to catch on!
And of course, Tibet is a great place to tour around with the cheap hotels nearby to book for a restful night.
