1, Choose a hospital: If you want to do it in China, don't listen to those advertisements and don't go to private hospitals. Expensive surgery may not be good. Let's find some more reliable public hospitals focusing on plastic surgery, such as Shanghai Ninth Hospital, which is quite famous. The charge is also real, and it is acceptable without counter-offer. There are also some famous private clinics that are not bad. Those who have become famous doctors. Of course, anywhere, surgery is risky.
2. Let me talk about the approximate cost of public hospitals: mandible 15000, cheekbone 15000 (generally need to be increased). The nose depends on what to do and the material of the prosthesis. Silicone is cheaper and bigger. It may range from more than 1000 to tens of thousands, depending on the material of the chin.
Sorry, I don't know which hospital in Korea is good, but I don't recommend that you go to Korea for the whole operation. The cost is not a small expense, many times more expensive than that in China. But the effect is not so much better. Korea seems to have a good sense of smell.
You can go to the forum to learn more about the situation and choose for yourself. But be careful.
