The central idea of the Avalanche is its first route. The form demands you to move with high momentum and it to crush your opponent to bulldoze over their defence. If they move back, you follow fast like a shadow, and do not give them any moment of rest. That’s why it is called the “Avalanche”. Your body movement and footwork have to fast and smooth and fierce. At a glance, you would appear to be a mad man, and that’s one characteristic of the Plum Blossom Mantis.
Every form has its central idea. You need to follow that idea when you practice, and the techniques recorded in a form are not that important at all. Therefore, you do not need to learn many forms and the forms do not need to be long. Learning too many complex and complicated form only prevents you from getting the core concepts.
Take the Avalanche for instance, if it was too long, and it demanded you to use explosive power in high speed through out, you would not have enough energy to finish the form as it was demanded. It does not matter how fit you are; your explosiveness and mental capacity for concentration would be spent within a minute under such intense demand. If you did not use explosive power, then you would not be following the idea of the form. Just remember, time is always limited no matter how much time you put it for practice. That is why you have to use time efficiently. To learn how to use certain techniques, it is always better and more efficient to learn them by sparring.
