Abstract：
We use the requirement of the chirality and complementarity in grand unified preon models to search for possible models.The general requirements to SU(N) grand unified preon models are:1) satisfying the requirement of the chirality;2) satisfying complementarity;3) giving at least three families of quarks and leptons.We mainly discuss the requirement of the chirality.We find that the model which satisfies the above three require ments is SU(10) grand unified preon model and we discuss this model in detail.
