I found out about it on YouTube, and among the places where I had consultations, I liked this one the most because the staff were kind and the manager made me feel comfortable. They did a CT scan, had CCTV, seemed to have an anesthesiology director, and said aftercare/AS was provided for 3 years, so I thought it was a responsible hospital.
During the consultation, the director pointed out things that other hospitals had not mentioned. I said I wanted to improve the front view of my nose, and since I have a relatively high nasal bridge, they did not recommend silicone. They also explained objectively about my nose condition, such as that the side area above my nose is large, so if the nasal tip is raised, the shape could end up looking like a jar. This kind of detailed explanation was a big help in deciding on the hospital.
