Sam Junwei Liao Investigating lecturers' perceptions of English Medium Instruction (EMI) may be a fruitful research subject since it can give insight into the experiences and perspectives of the instructors in charge of providing EMI in higher education settings. In particular, as the use of English as a medium of instruction has increased in China in recent years, researching lecturers' opinions of EMI can aid in understanding the obstacles and possibilities connected with this transition in language use.

The study might be valuable for Chinese educators and administrators involved in the implementation of EMI in higher education. It can, for example, aid in identifying areas where lecturers are confident and well-prepared, as well as places where they may want more assistance.

It can also reveal how lecturers are adjusting to the use of English as a medium of instruction, as well as the impact this change is having on their teaching and students' learning.

Furthermore, the research can benefit institutions by giving feedback on the EMI policy, the amount of teacher training, and support. It can also benefit policymakers because the study can assist to guide the development of EMI policies and strategies in higher education.

Overall, researching lecturers' impressions of EMI in China may be a significant study topic since it can give insight into the experiences and perspectives of the instructors who are in charge of teaching EMI and assist to understand the difficulties and opportunities.
