Abstract：
A new grand unified model containing the known three generations of quark and lepton in which hadrons are regarded as nontopological solitons formed from quarks is presented. According to the model leptons and quarks are the same in essence. The differences between them are caused by spontaneous symmetry breaking.When a quark is located inside a hadron, its properties will be the same as those of a known quark and its mass very small. When a quark is outside hadrons, its properties will be the same as those of a known lepton, its mass very large and it Will rapidly decay. Except defining charge Q0 and fermion number F0 which are exactly conserved, we also define interior colour, interior charge and interior fermion number approximatly conserved inside a hadron. The (L-B) conservation in the known SU(5) model corresponds to the fermion number number Fo conservation in the present model.
