The video has been widely shared across Chinese social media with the claim that the people in the footage had just undergone an anal swab. Authorities insist the procedure does not cause discomfort and would certainly not cause people to walk strangely as the video suggests. They also warned that social media users who spread conspiracy theories or fake news online will face legal action.
