1 Introduction
The tracking property has an important application in topological dynamical systems. In recent years, more and more scholars pay attention to it, and the relevant research results are shown in [1,2,3, 4,5,6, 7,8,9, 10,11,12, 13,14,15, 16,17]. Liang and Li [1] proved that the self-map
