  In the present paper, we study the existence of normalized solutions to the
following Kirchhoff type equations \begin{equation*}
-\left(a+b\int_{\R^3}|\nabla u|^2\right)\Delta u+V(x)u+\lambda
u=g(u)~\hbox{in}~\R^3 \end{equation*} satisfying the normalized constraint
$\displaystyle\int_{\R^3}u^2=c$, where $a,b,c>0$ are prescribed constants, and
the nonlinearities $g(u)$ are very general and of mass super-critical. Under
some suitable assumptions on $V(x)$ and $g(u)$, we can prove the existence of
ground state normalized solutions $(u_c, \lambda_c)\in
H^1(\R^3)\times\mathbb{R}$, for any given $c>0$. Due to the presence of the
nonlocal term, the weak limit $u$ of any $(PS)_C$ sequence $\{w_n\}$ may not
belong to the corresponding Pohozaev manifold, which is different from the
local problem. So we have to overcome some new difficulties to gain the
compactness of a $(PS)_C$ sequence.
