These are the ten principles of taijiquan, according to Yang style grandmaster Yang Chengfu.
１．虚霊頂頚
２．含胸抜背
３．鬆腰
４．分虚実
５．沈肩墜肘
６．用意不用力
７．上下相随
８．内外相合
９．相通不断
１０．動中求静
These principles deal with the movements of taiji, how taiji should be practised. They also affect how taiji is actually used. I will try to find time to explain each of them in more detail.
