After studying with his mentor, he realized that orthopedic knowledge is far more profound than he imagined.
For example, the source of human blood isn't the heart, but the bone marrow.
Moreover, the body's omnipotent cells also come from the bone marrow.
Bones not only serve as support for the human body, but also hold multiple significances. After hundreds of years of evolution, each bone has its specific function.
His graduate studies made him understand why major hospitals highly value academic qualifications, almost hiring based solely on them.
There is indeed a considerable difference in the knowledge level between undergraduates and graduate students.
Now he has the identity of a teaching assistant, vice leader of the emergency surgery team, and an in-service graduate student, which is evidently much higher than before.
The weight and status cannot be compared to the past.
