HanziPen  Suggested by fonatica 

I have a clue about this font, the name contains these words "Hanzi" and "Strokes". I searched "hanzi strokes font" and didn't find it. I saw this font from my friend's Macbook Pro running Mojave at the time (in case this is needed, and could be an older MacOS preinstalled font)

Even with these clues I couldn't find this font
