Did you know that in Tibet, sticking your tongue out is a way of greeting? This custom dates back to the 9th century during the reign of the unpopular King Lang Darma, who was known for having a black tongue.
After his death, people feared he might be reincarnated, so they began showing their tongues as a way of proving they weren’t the king. Over time, this practice evolved into a sign of respect and friendliness.
