By comparing the kinematic distributions of the LFV signal and the standard model (SM) background, we develop an optimized event selection criteria which can significantly reduce the background events. It is concluded that new $2 \\sigma$ upper limit of about $1.9 \\times 10^{-9}$ on $Br(\\tau \\rightarrow \\mu \\gamma)$ can be obtained at the CTF, which is beyond the capability of Super-B factory in searching $\\tau$ lepton rare decay.
