There was a doctor named Xu in Huamei, Shanghai. The technology is great. I've experienced it. In terms of price: Some choose ordinary methods, which are more invasive and require slower recovery. Some choose the endoscopic aesthetic method, which is less invasive and scar-free. However, because the surgical methods are different, the difficulty of the surgery is also different, and the equipment required for the surgery is also different, which also affects the price.
