Hùng Duệ Vương, the 18th king of the Hồng Bàng dynasty, had a very beautiful daughter named Mỵ Nương.
Sơn Tinh made a gesture with his hand in the air and trees instantly sprouted from the earth into a forest.
These unique wedding gifts included a nine-tusk elephant, a nine-spur cockerel, and a nine-mane horse - specialities all found on the earth and not the sea, a clear disadvantage for Thủy Tinh.
Early the next morning, Sơn Tinh arrived first, married Mỵ Nương and took her back to the Tản Viên Mountain, where he lived.
To protect the people, their properties, and belongings, Son Tinh created dikes to shield them from the rising sea.
This battle between the two Lords lasted for countless days but eventually, Thủy Tinh became weary and lowered the sea.
