Zhang Jia Ni has been exposed to the beauty of the skin and tried the ultrasonic knife.

Zhang Jiani revealed that he had received an ultrasonic knife to make his neck. The result was really painful because the ultrasonic knife could not be used for anesthesia. "After the trial, I decided not to try the second time again, and then spent money and then it hurts." Ultrasonic knives are a kind of wrinkle removal method. Actress Zhang Yuxi once described: "The ultrasonic knife is like a barbecue. Put the raw meat on the iron plate, and the high temperature will make it quickly thin and tighten."
