Abstract:Against the backdrop of China’s policy of seeking peace and development worldwide and its increasingly important role in world affairs, the internationalization of Chinese has become an irreversible trend. In this context, it is of great practical significance to sum up the practical experience and achievements of teaching Chinese as a second language (TCSL) in the past 70 years, and explore the “Chinese Solutions” in order to promote the internationalization of Chinese in the new era. Over the past 70 years, with the endeavour of generations of teachers of TCSL, great achievements have been made in teaching and research. From the 1950s to the 1970s, great achievements have been made in exploring the principles of Chinese teaching, which laid a solid foundation for the development of the discipline. From the 1980s to the 1990s, the teaching practice has developed extensively and intensively, and the disciplinary construction has unprecedentedly made great progress in all fields. In the 21st century, especially after the World Chinese Conference in 2005, the emphasis of TCSL has shifted to overseas, and remarkable achievements have been made. However, TCSL in China tends to be marginalized. So we should strengthen the leadership and planning of the discipline, promote the new development of TCSL in the new era, and provide more “Chinese Experience” and “Chinese Solutions” for the internationalization of Chinese.
