The slip is an obvious mark in retreat of the slopes. The Fengtan Reservoir's bank is one of the slopes. It's rather shaky, and does not mean slips. The headward erosion is being cut down by the brooklets along the joints. Its headward has been stretching to the river terraces. The terrace level is being broken up; The terrace level is better than the slip when it was cut by the brooklets,but It's not slip;the deluvial eluvial is bedding plane slip at the edge of the first terrace. Therefore,the saying about the four slips is discussable.
