Extracardiac: Large hospitals are generally divided into extracardiac and extracardiac. No matter outside the heart or outside the heart, the level and development prospect of general hospitals are average, and the income is average. Although cardiac surgery is very advanced, there are few hospitals that can perform major surgery, and the working face is narrow, which is not recommended.
Ophthalmology: As the saying goes, it is best to have a big hospital in ophthalmology, but the general hospital is not good and the income is good, but it also faces the problem of narrow job hunting.
Beyond plastic surgery: in China, the development is in its infancy, but large public hospitals are not as good as private hospitals, and this major mainly depends on the reputation of surgeons rather than the scale of hospitals, so it is difficult to develop, so it is not recommended.
Endocrine: It has basically become a specialty of diabetes and hyperthyroidism. Now there are more and more diabetic patients, and they are chronic diseases, and they are hospitalized repeatedly. No matter the size of the hospital, there is never a shortage of patients, and for the internal medicine department where there are many girls, boys are more popular and the income is good, but the internal medicine department has some ink on boys.
So generally speaking, I personally recommend orthopedics and endocrinology.
