We investigate the masses of light pseudoscalar mesons by the method based on a new anomaly free condition for axial vector current. By this viewpoint, the field theories discussed here do not have the U(1) problem. We calculate the masses of nine light pseudoscalar mesons, with theoretical result agrees reasonably good with experiment.
