In the context of increasing global connectivity and the development of China's One-Belt and One-Road policy, crossculture leading has become more and more common, more and more important for not only China but also other countries. Many MNCs start to put more efforts in improving their managers' cross-culture leadership in order to be more competitive when doing international business. Under such conditions, we reviewed the literature and research on cross-cultural leadership and selected it by searching three keywords: cross-culture leadership, cross-culture and crossculture management on Google Scholar and CNKI. Then, the selected research is divided into two major aspects: the qualities of an excellent cross-culture leader and ways of improving cross-culture leadership. We summarize the content of cross-cultural leadership and according to these contents, we also summarize the ways of improving cross-culture leadership, both two parts can be concluded in six parts, which mainly focuses on leaders' cultural adaption ability, leaders' communication skills, leaders' cooperation skills, leading skills, professional skills and leaders' personal characteristics. At the same time, we also find that the current research is all quite scattered from each other and among them lack a systematic link.
