Character or person???

Yes, since he was a real person.

Thank you for your answer, Aspara Gus. If he is not a real person, can't I use the word "character"? Thank you in advance for your additional answer.

Son JamesIf he is not a real person, can’t I use the word "character"?

Yes. Character would be appropriate if he were an imaginary person portrayed in a work of fiction, such as a novel or a play.

However, in other contexts, character can be used to refer to a real person regarded as eccentric, suspicious, or charismatic.

Is he still alive? If not, the tense should not be "has been."

Thank you for your kind explanation,Aspara Gus

He died a long time ago. He worked in 1 century B.C. Do I have to use a past tense there? He wrote a history book for the first time in Chinese history. I wanted to emphasize his existence. I think that his books still are influential. Even though it is like that, do I have to use past tense? I just want to know it more clearly. Couldn't you explain the tense to me a little bit more? Thank you in

He IS important if he still is considered extremely important.
He WAS important if he was significant then and but of lesser importance now.

But "has been" doesn't work.

Now I could understand your point. Thank you for your confirmation and teaching, BarbaraPA.
