Isn't there Xiangya Hospital in Changsha? It is an academic leader unit of burn plastic surgery in Hunan Province.
Of course, if you are not at ease, you can go to the nearest Chongqing Southwest Hospital (an excellent military hospital in burn department).
After the operation, it depends on your own plastic surgery area and degree.
Generally, try not to see the sun in the early days.
There is generally no problem in the later stage.
I wish you a speedy recovery.
