The Nanjing Sister Hong incident is a scandal that erupted in July 2025, involving a 38-year-old man from Nanjing, China, who allegedly masqueraded as a woman known as 'Sister Hong' and engaged in sexual activities with thousands of unsuspecting men. These encounters were reportedly recorded, and the explicit videos circulated online, sparking massive media coverage and internet meme mania. According to media reports, the man, surnamed Jiao, adopted the 'Sister Hong' persona online, luring men through dating apps by posing as a married woman. The fantasy of intimate relations with another's spouse proved irresistible to many, and Jiao's operation involved offering 'free sexual services' in exchange for gifts, rather than cash. Victims ranged from college students to foreign nationals, and some even returned for more encounters. The scandal blew up when these recordings started being shared and sold on various platforms, turning 'Sister Hong' into a viral sensation. Police have since arrested Jiao, charging him with the production and distribution of obscene material, and are working to scrub the internet of the illicit content. While rumors initially claimed over 1,600 men were involved, authorities have called this an exaggeration. The incident triggered a wide array of online reactions, from memes to AI-generated parodies. The 'Sister Hong' style even inspired fashion tutorials and commercial campaigns. On social media, the '紅姐' hashtag trended on Weibo with over 200 million views, and an augmented reality filter mimicking Jiao's bedroom became a hit on Instagram. Meanwhile, a Vietnamese stage play featured a character based on Sister Hong, drawing cheers from the audience. In a twist of real-life drama, some men were identified by acquaintances, leading to personal fallout, including a divorce filing by one man's spouse. The Nanjing Municipal Centre for Disease Control and Prevention offered STI screenings to those potentially exposed, though Jiao's own health status remains confidential.
