In 20000 BC, before the first history was recorded in writings, there had been already among people the legends and mythology about the origin of Viet nation from HUNG VUONG. These are stories on HONG BANG dynasty, offspring of dragon and fairy, bag of hundred eggs, eighteen kings of Hung Vuong dynasty, Son Tinh - Thuy Tinh's conflict, Thanh Giong's victory over An foreign aggressors, folk of betel and areca nuts, "banh chung banh day", watermelon ..... All these legends together can be regarded as a folk history. These historic legends were firstly collected and compiled by the contemporary authors' view. The two symbolic works of this aspect were Viet Dien U Linh by Ly Te Xuyen with a foreword in 1329, and Linh Nam Trich Quai by Tran The Phap in around end of Tran (1226), then edited by Vu Quynh and Kieu Phu in Le era (1428) with prologue in 1492-1493. According to one of the numerous legends concerning the origin of their state, a Vietnamese prince named LAC LONG QUAN came to Northern Viet Nam from his home in the sea. He married a princess from the mountain, AUCO, who is also described as the wife of a Northern Intruder (Chinese?), on the top of Mount Tan Vien, sometimes around 2800 BC Instead of the commonplace results of a union, the princess laid 100 eggs - when they hatched, a son emerged from each of them. Afterward, the parents separated because he was dragon from the sea, she was lady fair from the mountain. Therefore, the mother led half the progeny across the northern mountains, and became the ancestors of the Muong. While the remaining fifty followed the father to the sea and became ancestors of the Vietnamese. The most valiant of the sons was chosen to be the first of the eighteen HUNG VUONG kings. Lac Long Quan, a prince of the sea, and Au Co, a princess of the mountains, are regarded by the Vietnamese as their primal ancestors. Chu Nguyen
