Sometime during the Qing Dynasty a young beautiful woman by the name of Yim Wing Chun (嚴詠春) was engaged to marry. However, a military officer on a campaign of his entrusted territories spotted the young beauty and insisted she would become his bride. Already being engaged she protested his advance with results. Until the interference of the Shaolin Nun by the name of Ng Mui. Ng Mui promised the officer that Wing Chun would be his bride, if at the end of his campaign he would return and was able to defeat the young beauty in a fight. Full of confidence, the officer agreed to the terms. The Nun, recently escaping Siu Lam Temple in it's destruction, had witnessed a fight to the death between a Snake and a Crane. Utilizing what she had seen between the snake and crane and her prior Kung Fu practices, Ng Mui taught this newly formed system to the young woman. At the end of the officer campaign, the young Yim Wing Chun was easily able to defeat him. Even with his years of military training, Wing Chun was able to win, not by using brute strength and over baring power, but by using speed and superior angles. The same as witnessed of the snake and crane battle. The officer left in embarasemnt and Yim Wing Chun was left to marry Leung Bok-Chau.
