Abstract: Disclosed are mortise and tenon joint structures for Chinese characters formed by building members having the same or different configurations, and a method for inputting Chinese characters by using the building members. The Chinese characters are de-structured such that each Chinese character consists one or more radicals which are formed by the mortise and tenon joint structures or variants thereof. The variants of the mortise and tenon joint structures are formed by shift, rotation or combination of shift and rotation of the building members of the mortise and tenon joint structures. This establishes an inputting method between the Latin letters and Chinese characters.

Abstract: Disclosed are a Chinese character structuring member, a system of mortise and tenon joint structures of Chinese characters formed by the Chinese character structuring member and a method for inputting Chinese characters. An entity component of Chinese characters includes the following three structures: an entity component provided with a connecting mechanism at a middle and/or one end or both ends of the entity component configured to join with other entity components of the Chinese characters; an entity component provided with a connecting mechanism entity component extending from one end of the entity component to the other end of the entity component without exceeding the entity component of the Chinese characters; and an entity component provided with at least one connecting mechanism on the entity component that includes a plurality of sub entity components connected end to end and rotatable at the joint.
