If you are inexperienced and have no acquaintances or friends to introduce you, you must be careful. Be sure to shop around before you do it. These materials about real case evaluation are hard to find. Many doctors who are obviously incompetent will brag about their resumes, and many friends who don't know the real situation will be cheated. So generally speaking, we will give the user a case study to see which doctor is suitable for her, and they are basically doctors who have introduced for more than ten years, so there is basically no risk.
