Couples are facing a crackdown on any kind of physical intimacy at the Guangdong University of Foreign Studies, after a student murdered his girlfriend at the start of the term.
According to the local media, the woman was stabbed to death while she was alone in her room on campus.
A male student later turned himself in to police. Both were in the adult continuing-education programme.
The new rule is part of a campus-wide effort to weed out what university officials regard as improper behaviour.
A list of '11 improprieties' was published on the university's website last month, covering a range of behaviour, including class discipline, littering and relationships. Each student was also given a copy of the regulations.
According to the rules, couples are prohibited from kissing, hugging or holding hands on campus grounds.
The website says that the system was implemented to prepare teachers and students for an evaluation by members of the Central Ministry of Education, who are due to arrive next week.
