The COAT of ARMS representing Vietnam traditionally consisted of a shield having the stylistic representation of a dragon . . . a legendary and totemic animal of multiple symbolic significance. Also included on the Coat of Arms were the unicorn, tortoise and phoenix. They make up a quartet of traditional motifs and emblems of Vietnam.
The Dragon ("Long") in Vietnamese mythology is represented with the head of a camel, horns of a deer, eyes of a fish, ears of a buffalo, body and neck of a snake, scales of a carp, claws of an eagle, and feet of a tiger. A long barb hangs on each side of its mouth, and a precious stone shines brilliantly on its tongue. The summit of its head is decorated with a protuberance which is a sign of great intelligence. Finally, it has a crest of 81 scales running the entire length of its backbone.
A dragon breathes a smoke which can be transformed at will into fire or water. It lives with equal ease in the sky, in the water, or underground. Immortal, it does not reproduce, because the number of dragons always increases with the metamorphosis of the "Giao Long", which are fabulous reptiles 'half lizard and half snake' that automatically become dragons after ten centuries of existence.
The dragon does not incarnate the spirit of evil, Vietnamese consider the dragon a symbol of power and nobility, as the special symbol of emperors. The emperor was considered to be the son of Heaven. The dragon with five claws was found on the official dress of the emperor, and the dragon with four claws decorated the official dress of high dignitaries of the Royal Court.
