How do I change the "penmanship" from sans serif?

[iMore Question]

ever since I added "Chinese language" to my keyboards then removed it, my letters are now in plain lettering. Help out there? Thanks, Nanc

Welcome to iMore. How is the font different? I don't think adding a new language will change the font. Apple did change the font a while back. As far as I know, it can't be changed. You can add "bold text" in Settings and change the size.
