We want to investigate in a low energy QCD system, how about the shear viscosity over entropy and see when the system approach the possible phase transition what will shear viscosity over entropy of the system be? Find that when system approach the phase transition point, shear viscosity never increase below the lower bound suggested from string theory, and the tendency changes when approach the possible phase transition point.
