  Anomalous Hall effect (AHE) is important for understanding the topological
properties of electronic states, and provides insight into the spin-polarized
carriers of magnetic materials. AHE has been extensively studied in metallic,
but not variable-range-hopping (VRH), regime. Here we report the experiments of
both anomalous and ordinary Hall effect (OHE) in Mott and Efros VRH regimes. We
found unusual scaling law of the AHE coefficient $Rah=aRxx^b$ with b>2,
contrasting the OHE coefficient $Roh=cRxx^d$ with d<1. More strikingly, the
sign of AHE coefficient changes with temperature with specific electron
densities.
