Based on the rest frame defined by the \\oiii $\\lambda$5007 narrow emission line, a medium-strong positive correlation is found between the \\civ\\ blueshift and the luminosity at 5100\\AA\\ or the Eddington ratio \\leddR. A medium-strong negative relationship is found between the \\civ\\ blueshift and \\civ\\ equivalent width.
