In this paper, we use the Nevanlinna theory and normal family theory to study the converse Bloch principle. Our results improve the results of K.S. Charak, J. Rieppo. Also we add a necessary condition about a special differential polynomial and improve the result which was obtained by Xu, Wu, and Liao. Furthermore, we point this condition can not be omitted and we extend the result to a new case.
Keywords:Meromorphic function;Normal family;Nevanlinna Theory;Sharing values
