During the work of making the typical seismic atlas of the broadband seismic record of NCDSN Beijing station ,we found the first arrival phase that recorded in the far distance of epicenter 16°.8 earthquake was still the Pn , and the phase PnPn as the obvious characteristic semismic phase was recored continuously to the distance of epicenter about 30 degree. This paper tries to showe and prove the characteristics and the existence evidences of the teleseismic Pn and PnPn, and also tries to explain the reasons of the PnPn amplitude is much larger than the Pn amplitude several times.
