LEGEND OF THE WATERMELON

Once upon a time, the sixth son of King Hung Vuong the Fifth named An Tiem disobeyed the King’s order and was exiled to a deserted island. One day, he found a green fruit as big and round as a ball. He split the fruit into halves and found the inside of the fruit red. He dared not eat it because he was afraid it was poisonous. One day, An Tiem was so tired and thirsty that he tasted the fruit and he found out that it tasted delicious. He tried to grow the plant around his house then. Soon the whole island was covered with the green fruit. An Tiem carved the island’s name and his own on some of the fruit and threw them into the sea. Later, seamen found the Strange fruit with An Tiem’s name floating in the sea.

Soon, words about the fruit reached the continent and many merchants tried to find the way to the island. This then turned the deserted island into a busy island. King Hung Vuong was very proud of having a son who was brave and strong enough to overcome difficulties without anyone’s help. An Tiem was immediately summoned back to the court. He brought his fruit with him to offer the King, his father. The King gave him his crown and An Tiem became King Hung Vuong VI. Since then the fruit which was called “dua hau” and has become the symbol of luck; people often offer it to relatives and friends as a New Year present.
