As the most basic physical essence of Tuina manipulation isforce, the classification of manipulations could not be separated itself from the force. And the acting way of external force should be regarded as the basis and ROFlTI in classifying manipulation. Meanwhile, the aim of classification is convenient for generalizing and expounding the general and the specific rules of the manipulations, and thus serving for the research, systematization, teaching and application of manipulations, and providing a framework for establishing the theoretical system of Tuina manipulations．Therefore, the classification should be both scientific and sucessive. We should respect the history and present condition, can not classify manipulations only for the sake of classification, thus avoiding theoretical confusion.

As regards to the mutual acting ways between the manipulations and human body, they can be divided into two types. One is that the force of manipulation is directty transferred to the local tissues through the touch of the hand, and causing deforming and wave moving due to inner pressure of the local tissues. In the other manner, manipulation force acts on the ligaments of distant joints by means of the bone lever and the tension of soft tissues, and causing changes in the moving states of the joints. Such a way of classification is just set up on this biomechanic basis. The former is termed as "Pressing Category’’ while the latter as "Rectifying Category", which shows our respect to the history.
