Ле Лой
Lê Lợi revolted in 1418 against the Ming Dynasty, who had invaded and occupied Vietnam in 1407. Initially the military campaign against the Chinese was only moderately successful. While Lê Lợi was able to operate in his home province of Thanh Hóa, for the first 2–3 years, he was unable to muster the military forces required to defeat the Ming army in battle. As a result, he waged a guerrilla campaign against the large and well organized Chinese army. According to legend, to help Lê Lợi, a local God, the Dragon King (Vietnamese: Long Vương) decided to lend his sword to Lê Lợi. But there was a catch; the sword did not come straight to him in one piece. It was split into two parts: a blade and a sword hilt.
