One for Essence

不怕千招會，就怕一招精

Do not fear the thousand skilful moves, fear the perfect one 

Old practices are about changes, not multiplicity.

Tiger Lady, Lady Meets Tiger

In a Feminine and Masculine principles (Yin and Yang) relation, there are always connections with the Feminine and the Masculine and one principle also always exists inside the other one. Lady is obviously the Feminine while tiger the Masculine. In this particular case, it is mainly dealing with the issue of check and balance as well as being able to instantly switch from one state to another. Therefore, as ladylike one would look, it will still be a spirited and unpredictable one who would fiercely preserve her integrity. Furthermore, using the absence of empathy will be one of the way to calmly endure insults, threats and bulling. As far as the tiger is concerned, as wild and insane one would behave, self-control and vigilance would remain. Furthermore, as the oxymoron method dictates, the more fierce, cruel and insane one was outside the more calm, smiling and mild one had to be inside.

Changing Doors

One of the eldest texts known describing the martial arts theory is called "The Lady of Yue Talks About Fencing", a passage from the historical records called "Spring and Autumn Annals of Wu and Yue" written by Zhao Ye (?-around 83 A.C.). Later literary works inspired by this lady fencer figure, such as the one of the famous Hong-Kong writer Jin Yong called "Sword of the Yue Maiden" has made this passage quite famous, more than the one about archery that follows a few paragraphs later. Indeed, introducing a lady fencer in a male chauvinistic society which forbade teaching girls because they would marry into another family and having her teacher being an ape, a white gibbon, cannot but struck one's imagination.

Training boxing without stopping on the legs, certainly a reckless person.

Legs and up to the waist are the roots, the essential part of training.
