Liu Qing opened a nail salon in Yingchuan Road, Longzhou Street, Longyou County. On August 3rd, 20 16, Liu Qing started to operate medical beauty services in his own nail salon without obtaining the qualification of a medical practitioner and the practice license of a medical institution. Wang He, who is less than 30 years old, is a familiar neighbor. In order to become more beautiful, Wang asked to inject hyaluronic acid for rhinoplasty. Unexpectedly, Wang suffered from hand numbness, drooping right eyelid, blurred vision and other adverse reactions after injecting hyaluronic acid, and was subsequently taken to hospital for treatment. Later, although Wang was transferred to several hospitals for treatment, he was never able to return to heaven and his right eye was completely blind.
