It is advanced firstly that trilingual education is based upon the multicultural education pedagogically and upon the development of bilingual education theoretically and practically. In addition, the research into trilingual code-witching becomes all the more important and significant due to the fact that trilingual education is a newly-developed research subject. The present study is of considerable significance in that it not only enriches the research of code-switching both in general setting and in classroom context, fosters conceptualization and implementation of trilingual education, but provides the implications for the EFL education for ethnic minority learners.
