Abstract
Language variation in a context is influenced by various factors. While there has been some research regarding English language variation, there has not been much research pertaining to Chinese variation (Gao, 2017; Xu, 2015). In the present study, we examined different language usages among different social classes of Tianjin in China in order to understand the social meaning of a language and to help teachers understand the practical uses of language in teaching Chinese as a foreign language. We collected data from 206 shoppers and 10 different employees working in five stores through multiple observations, reflections, and field-notes. The results indicated an overall variability among different social classes and significant use of greeting and bargaining expressions in communication at different levels of the society in Tianjin. Through the present study, we also provide pedagogical implications for language educators in teaching practical uses of Chinese as a foreign language in United States schools.
