We consider the Friedberg-Lee symmetry for the quark sector and show that the symmetry closely relates to both quark masses and mixing angles. We also extend our scheme to the fourth generation quark model and find the relation |V{sub tb}{sup '}|{approx_equal}|V{sub t}{sup '}{sub b}|{approx_equal}m{sub b}/m{sub b}{sup '}<{lambda}{sup 2} with {lambda}{approx_equal}0.22 for m{sub b}=4.2 GeV and m{sub b}{sup '}>199 GeV.
