Story Summary
Discover the tragic Vietnamese legend of My Chau and Trong Thuy, a classic tale of a magic crossbow, misplaced trust, and the fall of the ancient Au Lac kingdom.
King An Duong Vuong ruled the kingdom of Au Lac, protected by the magical Co Loa Citadel and a divine crossbow trigger gifted by the Golden Turtle, Kim Quy. This weapon allowed him to defeat any invader. Seeking peace, the rival King Zhao Tuo sent his son, Trong Thuy, to marry An Duong Vuong’s daughter, My Chau. The two fell deeply in love, but Trong Thuy had a secret mission: to find and neutralize the magic crossbow. My Chau, blinded by love and trust, showed her husband the sacred weapon. Trong Thuy secretly replaced the divine claw with a fake and returned to his father. Zhao Tuo immediately launched an invasion. When An Duong Vuong went to fire his crossbow, it failed. Realizing he was betrayed, he fled toward the sea with My Chau behind him. Along the way, My Chau dropped goose feathers from her cloak to guide Trong Thuy to her. At the water's edge, the Golden Turtle appeared, declaring, 'The enemy is right behind you!' Realizing his daughter's accidental betrayal, the King executed her before disappearing into the sea. Trong Thuy, finding his wife dead, was consumed by grief and drowned himself in a well. Legend says her blood turned into pearls, which shine brightest when washed in the water of that very well.
