  In this paper, we will use the normalized intetral Ricci curvature to
investigate Liouville type property of $ p $ harmonic function on Riemannian
manifold. secondly, we will use the BiRic curvature to obtian Liuville theorem
for $ p $ harmonic function or $ p $ harmonic 1 form. Lastly, we we will use
the BiRic curvature to obtian Liouville theorem forharmonic $ q(q\geq 2)$ form.
