Chinese has a rich and diverse vocabulary of terms, especially verbs, expressing power relationships. This paper selected 25 power relationship terms from the Chinese Proficiency Scale for International Chinese Education, and used a true-false format to test the differences in acquisition between international students from Confucian cultural circles and those from non-Confucian cultural circles. The study found that: (1) The acquisition levels of both groups are generally behind that of ordinary vocabulary; (2) There is a significant difference in the acquisition levels between the two groups, with the former performing better than the latter; and (3) There is a significant difference in the acquisition of these terms in administrative and family settings between the two groups, with the former performing better than the latter, but there is no significant difference in the acquisition of terms in other settings such as education. In response to these findings, the paper used interview data to provide mutual confirmation, and applied theories related to learning input, language transfer, and cultural circles to analyze and interpret the results. Finally, the paper made targeted suggestions for the teaching of power relationship terms.
