Hello, my friend, if you are below 18, you need your parents' signature! But I suggest you choose a regular hospital! Don't choose to know the clinic in order not to let your parents sign it, which will not only make the operation bad, but also hurt your health seriously! If you are in Yunnan, I recommend you to go to Renai in Lido, Kunming, Yunnan. You can consult them specifically, official website! I wish you the best of health!
