Before revision:  We make use of the Finsler metrics with Randers form, by which the asymmetric and anisotropic measures of the geodesic curve length are taken into account to avoid the shortcuts and leaking problems.
After revision:  We make use of the Finsler metrics with Randers form, through which the asymmetry and anisotropy enhancements can be taken into account to avoid the shortcuts and leaking problems.
