The introduction is in first person and the text is in third person.
What would it be like for a medical student to travel to ancient times? Use your modern medical knowledge to treat illnesses and save lives? Oh, maybe, but that would definitely not be me. I am an imaging major. Not to mention how I usually study, even if I have a photographic memory, I would just stare when I come here. Ha, where can I find a CT or MRI? By the way, the technician also gave me a thank you (smile).
There is no other way, just take it one step at a time.
Purpose: Study hard, treat illnesses and save lives
