We study the screening length of a moving heavy quarkonium (i.e., 
pair) at finite temperature and chemical potential using a soft wall AdS/QCD model with conformal invariance broken by a background dilaton. We discuss the pair’s axis parallel and perpendicular to the hot wind, respectively. It turns out that for both cases the presence of confining scale increases the screening length, reverse to the effects of chemical potential, velocity and temperature. Moreover, the effects of confining scale and temperature on the screening length for the parallel case are virtually the same as for the perpendicular case, but the effect of velocity on the screening length is more pronounced for the perpendicular case when the velocity is large.
