Lạc Long Quân

Lạc Long Quân (Chữ Hán: 貉龍君; "Dragon King of Lạc"), also known as Sùng Lãm (崇纜), is an ancient king of the Hồng Bàng dynasty of ancient Vietnam. Quân was the son of Kinh Dương Vương, the king of Xích Quỷ. He is the main figure in the Vietnamese myth of Lạc Long Quân - Âu Cơ.

According to the myth, Lạc Long Quân married Âu Cơ, a mountain goddess. She gives birth to a sac containing 100 eggs from which 100 children were born; this is the origin of the Vietnamese people. One day Lạc Long Quân told Âu Cơ: "I am descended from dragons, you from immortals. We are as incompatible as water is with fire. So we cannot continue in harmony." This said, the husband and wife parted. The man went to the seawards with 50 of their children, while his wife went to the mountainous region with the other half of the clan. The eldest son, who followed his mother, later installed himself as Quân's successor.
