Keywords: Homoclinic Class | Dominated splitting | chain recurrent class
We show that there exists a generic subset $R$ among the $C^1$ diffeomorphisms set which are $C^1$ far away from tangency, such that for $f \in R$ and any non-trivial chain recurrent class $C$ of $f$, if $C\bigcap P_0^*\neq \phi$ then $C$ is a homoclinic class contains index $1$ periodic point and there are a family of sources converge to $C$ in Hausdorff topology.
