A Hexad Preon model where leptons, quarks and W Z bosons are composite is proposed. Six Hexad Preons transform under U(3)⊗ U(3) local gauge theory which is identified with U(1)Q⊗ SU(3)C⊗ SU(3)f⊗ U(1)w. All salient features of the standard model can be obtained from the compositeness of leptons and quarks: There are exactly six quarks and six leptons with evident three families (generations); All quantum numbers of leptons and quarks can be given out of that of preons; QED and QCD are given by electro-strong interaction U(1)Q⊗ SU(3)C ; The weak interaction is residual "Van der Waals" forces between preons and dipreons. It is shown that all processes in standard model are just reshuffle of preons. In addition, a possible dark matter candidate is presented. Other questions like the electroweak symmetry breaking, the spin of fermions, the origin of quark and lepton mixing, etc., are also addressed.
