We investigate the invariant mass distributions of via different rescattering processes. The triangle singularity which appears in the rescattering amplitude may simulate the resonance-like bump around 5568 MeV. However, because the scattering is supposed to be weak, if the pertinent background is much larger, it would be hard to ascribe the observation of X(5568) to rescattering effects.
