Using the conformal embedding on the torus, we can express some characters of
SU(3)3β in terms of SO(8)1β characters. Then with the help of crossing
symmetry, modular transformation and factorization properties of Green
functions, we will calculate a class of correlators of SU(3)3β on arbitrary
Riemann surfaces. This method can apply to all k>1 WZW models which can be
conformally embedded in some k=1 WZW models.Comment: 19 page
