Taiwan's China policy body is looking into claims that a teacher from mainland China kept calling the island "China Taiwan" in a university class, a case that touches a raw nerve over Beijing's influence on campus.

• A student posted online that a woman claiming to be from Jiangxi, China repeatedly used the phrase "China Taiwan" during the first international trade class of the term at a private university in Kaohsiung.
• When a student who had served in the military asked whether she held a Taiwan residency permit, she dodged the question and insulted him instead.
• The Mainland Affairs Council said anyone teaching at a public or private school must have Taiwanese status, though visiting professors and doctoral researchers are exempt.
• Deputy head Liang Wen-chieh said the address in the post narrows down which school it is, but officials cannot confirm it yet and are asking the public to send in details.

Outlook: Officials plan to identify the school and check whether the teacher was legally allowed to teach, which could turn a social media complaint into a formal case.
