Code switching occurs when a language user alternates two or more languages according to different time, places, contents, objects, and other factors. For example, code switching may occur in a multilingual family or in an immigrant family.<ref>{{Cite journal|last=Juyoung|first=Song|date=March 2019|title=Language Socialization and Code-Switching: A Case Study of a Korean-English Bilingual Child in a Korean Transnational Family|journal=International Journal of Bilingual Education & Bilingualism|volume=22|issue=2|pages=91–106|doi=10.1080/13670050.2016.1231165|s2cid=151966199}}</ref> That is to say, the capability of using code switching, relating to the transformation of phonetics, words, language structure, expression mode, thinking mode, cultural differences and so on, is needed to be guided and developed in the daily communication environment. Most people learn foreign languages in the circumstance filled with the using of their native language so that their ability of code switching cannot be stimulated, and thus the efficiency of foreign language acquisition would decrease. Therefore, as a teaching strategy, code switching is used to help students better gain conceptual competences and to provide rich semantic context for them to understand some specific vocabularies.<ref>{{Cite journal|last1=Cahyani|first1=Hilda|last2=de Courcy|first2=Michele|last3=Barnett|first3=Jenny|date=May 2018|title=Teachers' Code-Switching in Bilingual Classrooms: Exploring Pedagogical and Sociocultural Functions|journal=International Journal of Bilingual Education & Bilingualism|volume=21|issue=4|pages=465–479|doi=10.1080/13670050.2016.1189509|s2cid=147719529|url=https://ap01.alma.exlibrisgroup.com/view/delivery/61USOUTHAUS_INST/12142960180001831}}</ref>
