The medical community is known as a "world," and every world has its own rules and sayings.
Both Chinese and Western medicine value lineage and theory.
Since ancient times, Chinese medicine has featured a multitude of schools, from the Treatise on Febrile Diseases to the Earth-supplementing school of the Jin and Yuan dynasties, the Yin-nourishing school… to the subsequent school of Warm diseases, all brimming with the development of diverse theories.
The same goes for Western medicine; since the Republic of China era, modern medicine has flourished with the influx of Western medical science, putting on a "Western medicine" coat.
Surgery, as a primary treatment method in medicine, is also filled with various thoughts and doctrines.
Therefore, having a mentor is like having someone to lead the way.
