  In this work, a correspondence between black hole solutions of conformal and
massive theories of gravity is found. It is seen that this correspondence
imposes some constraints on parameters of these theories. What is more, a
relation between the mass of black holes and the parameters of massive gravity
is found. Indeed, the acceptable ranges of massive gravity parameters ($c_{1}$\
and $c_{2}$) are found. It is shown that by considering the positive mass of
black holes, some ranges of $c_{1}$\ and $c_{2}$ are acceptable.
