Emperor Hung-Vuong had many sons. Some pursued literary careers. Others excelled in martial arts. The youngest prince named Tiet - Lieu, however, loved neither. Instead, he and his wife and their children chose the countryside where they farmed the land.

One day, toward the end of the year, the emperor met with all his sons. He told them whoever brought him the most special and unusual food would be made the new emperor. Almost immediately, the princes left for their homes and started looking for the most delicious food to offer the emperor. Some went hunting in the forests and brought home birds and animals which they prepared into the most palatable dishes. Some others sailed out to the open sea, trying to catch fish, lobsters and other much loved sea food. Neither the rough sea nor the violent weather could stop them from looking for the best gifts to please the emperor.
