[1] In legend Chử Đồng Tử appeared on a yellow or golden dragon to Triệu Quang Phục the sixth-century resistance leader.
Upon discovering the youth, the Princess reckoned that this meeting must be fate, and proposed to Chử.
Whilst on a caravan or business trip, he docked at an island on the sea where he met a sage named Phật Quang (佛光).
Upon returning to his wife and wandering lifestyle, one day the couple found themselves in a vast field with no shelter under the pouring hail.
The spot where the castle once stood is now called Nhất Dạ (meaning One Night).
