A Chinese influencer, known only as Hua, has sparked controversy with his popular Douyin cleaning tutorials. Claiming to be a senior researcher at a Guangdong biotechnology institute, Hua boasts over 300,000 followers captivated by his unconventional methods for removing bloodstains and dissolving bones. His techniques, demonstrated in short videos, range from using hydrogen peroxide and toilet cleaner to eliminate bloodstains from bathroom floors, to employing toothpaste and even luminol (a forensic reagent) to clean bloodstains from clothing. Perhaps his most unsettling demonstration involves dissolving chicken bones using a mixture of drain cleaner and hot water, explaining the chemical process with unsettling detail. He also showcases fingerprint extraction from phone screens using talcum powder.
While Hua insists his videos offer practical household cleaning solutions, the content has generated a polarized response on Chinese social media. Many viewers express concern that his techniques could be misused by criminals, with comments highlighting the potential for his tutorials to become a guide for concealing evidence. The use of luminol, a chemical typically used in forensic investigations, is a particular point of contention.
Conversely, some viewers praise Hua for his practical advice and helpful cleaning tips. They express confidence in his intentions, believing he wouldn’t encourage illegal activity.
In response to the backlash, Hua’s research institute has defended his work, stating its focus is on popularizing science and promoting safe cleaning practices, vehemently denying any intent to incite criminal behavior. However, a forensic scientist voiced apprehension regarding the potential misuse of techniques showcased in the videos, specifically mentioning the risk of criminals using them to cover up crime scenes. A legal expert, while acknowledging the videos don’t directly promote criminal activity, couldn’t fully dismiss the concerns.
The situation highlights a grey area within the realm of online content creation. In China, teaching criminal methods carries a significant penalty of up to 10 years imprisonment, further emphasizing the gravity of the concerns surrounding Hua’s videos and prompting ongoing debate about the ethical implications of such content.
