As for the written exam for the senior professional title, that is just the easiest first minor hurdle.
Dr. Shi should be around 39 to 40 years old.
Some doctors with good talent, solid foundation, and luck might get promoted to a senior professional title at 38, but there are very few of them.
Many people would be grateful to get such a promotion before the age of 45.
Why add good luck?
Because when choosing research topics, if you can hitch a ride on a big shot's coattails, participate in a decent project, or get tasked with heading an ordinary project.
These good fortunes require luck and character to achieve.
Dr. Shi being promoted to senior professional title at 40, and at a highly competitive major hospital like Tu Ya, is definitely a very successful transition.
Zhou Can went through the trouble of looking into this matter in preparation for his own future professional evaluations.
A man knows his own situation best.
