There are indeed differences in different fields in the medical field around the world, which is inseparable from the multiplicity and rarity of local diseases. For example, at present, there is still a big gap between China's labor protection conditions and developed countries, which directly leads to relatively many industrial accidents, so China's medical level in the field of replantation of severed limbs and burns is in the forefront of the world; Black people in Africa don't get appendicitis, so surgeons in many hospitals in Africa don't do appendectomy and so on.

Plastic surgery in Hong Kong has been carried out several decades earlier than that in China, so the level of plastic surgery hospitals in Hong Kong is indeed higher than that in China.
