I'm on Big Sur 11.2.2
Pages is able to use this font:
I want to add this font to ImageMagick, but I can't find it anywhere. I was able to find fonts in only two locations - one is Macintosh HD/System/Library/Fonts -- which contains most (but not all!) the fonts I see in Font Book. The other is Macintosh HD/Library - which contains just one symbolic link to a font living in Macintosh HD/System/Library/Fonts/Supplemental - (which does not contain the font I am looking for). Moreover, the folder /Users/'user_name'/Library/Fonts is empty.
So the question is obviously: Where is the Kaiti SC font?
