By assuming one parameter of the Wong formula, the curvature of the potential barrier, as an energy-dependent one, namely 
, a modified-Wong formula has been developed. Here, 
is an additional adjustable parameter and 
becomes the curvature at the top of the barrier, 
. This modified-Wong formula, with four parameters, reproduces fusion excitation functions very well for many light to heavy systems across the whole energy range, including fusion hindrance phenomenon.
