Based on a large Fermi blazar sample, the blazar sequence (synchrotron peak frequency ν\rm peak versus synchrotron peak luminosity L\rm peak) is revisited. It is found that there is significant anti-correlation between ν\rm peak and L\rm peak for blazars. However, after being Doppler corrected, the anti-correlation disappears. The jet cavity power (P\rm jet) is estimated from extended radio luminosity. So it is free of beaming effect. We find that there are significant anti-correlations between P\rm jet and beam-corrected ν\rm peak' for both blazars and radio galaxies, which supports the blazar sequence and unification of blazars and radio galaxies (an alternative relationship is the correlation between jet power and γ-ray photon index).
