Abstract
With help of the recent developments in the heavy quarkonium physics, we reexamine the long distance(LD) effects in dominantly from the charmonium resonances J/Ψ and Ψ through the decay chains B Xs J/Ψ(Ψ) Xs e+ e-. We find that the resonance to nonresonance interference are reduced substantially.
