Conformal blocks are essential ingredients for calculations of observable, that is correlation function, in conformal field theories (CFTs). The conformal blocks for more than four external operators are interesting because of higher-point conformal bootstrap and the AdS/CFT correspondence.  In this talk, we will show a set of Feynman-like rules to write down closed form expressions for scalar M-point conformal blocks with scalar exchange in any topology. These rules can be partially obtained from the Feynman rules for the corresponding Mellin amplitudes. and can be proved by induction.
