Pan Sheng spread malicious rumors about Lin Yiran among both boys and girls, claiming she had multiple boyfriends, spent time with disreputable men, scammed boys for money, and lived a shady off-campus life. The rumors escalated from ambiguous comments in the dorm restroom to exaggerated claims. The campaign was motivated by Pan Sheng's jealousy after Lin Yiran outshone him and was suggested as class president.
