The tiger boxing to build up one's bones: when practicing, you should build up the breath throughout the body, with the arms and waist solid, and arm pit strength exuberant. You should also keep this breath through the whole process, with every one of your movements powerful and majestic, your eyes glaring and the top of the head [possibly a misprint of "neck"] hardened, looking like an angry tiger pouncing out from the forest, as if pushing the mountains aside with its front paws.
