Ive been learning some Wu style from a long term student of Ma Yueh-Liang and Wu Ying-hua, he calls the movement "Tiger and leopard spring to the mountain". In the book by Wu Ying-hua 'Wu style Taichichuan - forms, concepts and application of the original style' it is refered to by the same name.
Just putting this out there to say that cjurakpt is not the only one who is using the leopard in the name.
Up and down, forward and backward, left and right, its all the same. All of this is done with the mind, not externaly.
