Michael Palin at Bhutanese festival in the Himalayas - BBC

To make the story short, it was that monk who brought down the Great Tibetan Empire to the end

(unintentionally)
After the assassination of King Langdhar, Tibet broke apart into pieces and never rose up again

under one king (except spiritual leaders)

If you don't know at least don't miss translate the ceremony...... traveling in bhutan and Northern india i realize how vast Tibet once was...... Its a shame that it is a Big giant Chinese prison now......

China and Chinese out of Tibet Now..... Leave the Holy land you don't belong and deserve to be in holy land atheist blood sucking chinese

A saint once wore the long sleeve to assisinate an anti-buddhist king in Tibet.
It's related to Bhuddhisms' History. A long story and complecated.

shes right .. that is the black hat assassin dance.

dude.but don't claim that you discovered Bhutan like how Columbus lied to the west.

I love to live there, simple way of life.

in ancient Bhutan, courtiers worse long sleeves. Sort of like a japanese kimono. It was deep enough to conceal a bow, which was used to assasinate someone.
