While we are on the subject of flags, permit me to note that while most people believe the Tibetan flag was designed by H.H. the Thirteenth Dalai Lama, it was in fact designed by the Japanese Buddhist priest Aoki Bunkyo in 1912, and transmitted to the Thirteenth Dalai Lama by Yajima Yasujiro, during his mission to Tibet 1913-1919.
