Vinh Ha Long
'Bay Of The Descending Dragon'
History shows that Hạ Long Bay was the setting for local naval battles against Vietnam's coastal neighbors. On three occasions, in the labyrinth of channels in Bach Dang river near the islands, the Vietnamese army stopped the Chinese from landing. During the Vietnam War, many of the channels between the islands were heavily mined by the United States navy, some of which pose a threat to shipping still today.
