"Globalization" and "Internationalization" have become an inevitable trend in the 21st century. Cultivating internationalized talents requires that the horizons of teachers in colleges and universities should be internationalized. Internationalization of horizons means that one should have thinking, mind and vision of internationalization. It also means internationalization of competitive ability for communication and cooperation. Teachers in colleges and universities must establish a strong sense of internationalization, and participate in international exchanges and dialogues. They should also learn to resolve problems under international multicultural circumstances. Internationalization of university teachers is the need of national talent development strategy, the inevitable choice of universities, the tie of university students' international horizons, and it is also in line with the current reality of University teachers. Colleges and universities should pay attention to their own international Outlook, establish a favorable international system to facilitate the development of teachers' international horizons. Meanwhile, the University should intensify training for home teachers, encourage the local teachers to go abroad and the foreign teachers to come in. "Globalization" and "internationalization" have become an inevitable trend in the 21st century. With the advancement of economic and political integration, education, particularly higher education's integration process is also getting faster. In order to meet the needs of economic and social development, higher education must actively train more talents with ideals, beliefs, pursuit, knowledge, and international horizons. Thus, some people with insights have advocated, "University students need to have international horizons", "Graduate students should have international quality." These are undoubtedly advanced ideals of higher education. But without teachers with international horizons, this good wish will never become ture. Therefore, internationalization of the horizons of teachers in colleges and universities must be accomplished.
