The purpose of this study is to find out the safety crisis of Chinese international students studying in Korea and how to improve safety perception. After COVID-19 as a sudden public event, safety perception and education on public health should be strengthened. Although China is taking many protective measures for the safety of international students, not only the popularity of 'health bags' is high, but also the publicity needs to be improved. The survey results showed that first, it is necessary to establish a mechanism for assessing student safety perception, adjust the focus of education, identify the main factors affecting student safety, and timely and effectively remove the pressure of the epidemic on students. Second, it is necessary to continuously update the safety protection contents for international students. Third, safety education for international students should be thoroughly conducted and attention should be paid to emergency management resources. Fourth, it is required to promote the timeliness and efficiency of information update and to establish a broad and effective information communication channel.
