Liu, who usually has no financial resources, wants to use people's demand for medical consultation to cheat money. So, he found some hospital vibrato videos from the Internet and forwarded them to his account. He found a photo of a middle-aged doctor on the medical platform and posted a video of the doctor's operation on Tik Tok, and changed his QQ, Alipay and WeChat account photos into photos of middle-aged doctors to attract others' attention.
