  Using a recent global analysis result after the precise measurement of
$\theta_ {13}$, a possible Herimtian neutrino mixing ansatz is discussed, the
mixing matrix is symmetric and also symmetric with respect with the second
diagonal line in the leading order. This leading order ansatz predicts
$\theta_{13}=12.2^\circ$. Next, consider the hierarchy structure of the lepton
mass matrix as the origin of perturbation of the mixing matrix, we find that
this ansatz with perturbation can fit current data very well.
