Two students at one of China’s most prestigious universities were issued warnings for distributing LGBTQ rainbow flags, highlighting how the nation’s increasing intolerance for sexual diversity is extending further into campuses. The pair were reprimanded for placing 10 handheld flags on a table at an on-campus supermarket in Beijing on May 14 alongside handwritten notes encouraging people to take the items, according to a person familiar with the incident who asked not to be identified publicly discussing a sensitive issue. That evening, Tsinghua University representatives told the pair distributing the flags was in possible contravention of school rules, the person said. About a month later, one of the students attended a meeting with school staff to discuss the incident.
