A local legend tells the following tale of the origins of Ha Long Bay:
“Long time ago, the Viet people were attacked by foreign aggressors. The Jade Emperor sent the Mother Dragon and her band of Dragon Children to help the Viet people fight the invaders. While the enemy vessels were launching massive attacks against the mainland, the dragons descended in flocks from the sky. They spat out innumerable pearls which changed into jade stone islands the moment they touched the water. These islands linked together to form firm citadels that checked the enemy’s advance and smashed their vessels to pieces.
After the invaders were driven out, Mother Dragon and her Dragon Children did not return to Heaven but stayed on earth, right at the place where the battle occurred. The spot where the Mother Dragon landed was Ha Long, and where the Dragon Children came down was Bai Tu Long
