2. The Second Artillery General Hospital of the People's Liberation Army had this activity, so you can consult it.
Some cities can enjoy non-treatment, so I won't list them one by one, because I don't know where you are.
Explain that the cost of this operation is not high. Might as well spend some money to make up for it. The scar will be lighter. After all, it is free. Personally, I don't think it will be repaired very well.
Personal advice, for reference only!
