So far, question words in Chinese have always appeared at the end. But with "shei" I saw sentences like
Shei shi nide baba?
So can it be used at the start or end of a sentence? Can we say
Nide baba shi shei?
as well? And also "Shei shi nage ren?" or "Nage ren shi shei?" (Who is that person?)
Is this restricted to shei or can it be extended to other question words like shenme, zenme, duoshao and nali/nar though words like ma and ne I know are always placed at the end?
Edit: I'm confused by this:
Translate this sentence
谁是你的爸爸
[your] [Wang] [individuals] [how] [mornings] [is] [dad] [Who]
(screenshot)Translate this sentence
Who is this person?
谁是这个人?
Oops! That's not correct.
这个人是谁?
