The “deaf-dumb” phenomenon whereby students desist from using the target language in classrooms is still prevalent in China today. Few students in English Medium Instruction (EMI) universities in China actively use English to communicate during instruction. Promoting grit skills could boost students’ self-confidence to enjoy learning a foreign language and communicate more. Data were collected from 85 undergraduates using Grit Scale-Short scale and the Chinese version Foreign Language Enjoyment (FLE) scale. Correlation and regression analyses evaluated the relationship between the variables and revealed a significant correlation between grit and FLE. The T-test showed moderate grit levels among participants, with M=3. While the correlation analysis showed a shallow and positive correlation (r=.276, p=0.010), the linear regression test revealed that a unit increase in the grit scale would contribute to a 0.276 growth in positive attitude toward FLES (β=0.276, p=0.010). This result implies that promoting grit skills could increase FLE. Hence engaging students in frequent self-reflection to boost self-confidence, lower anxiety, and increase self-motivation to use the language often is vital. Moreover, instructors should be caring and patient, give frequent, meaningful, and timely feedback on work completed and break large tasks into smaller chunks to motivate students to work passionately towards achieving set long-term goals.
