Copy the “Public” folder and paste it inside of your Baldur's Gate 3\Data
Put your custom font files in Baldurs Gate 3\Data\Public\Game\GUI\Assets\Fonts\Replacers

Baldurs Gate 3\Data\Public\Game\GUI\Theme\Keyboard.Fonts.xaml
And modify this line
<FontFamily x:Key="DefaultFont">/Assets/Fonts/Replacers/#ZhunYuan</FontFamily>Make sure the font name is the same as the actual name of the file. The config does not recognize Chinese font names it seems.

LXGW Wenkai also looks realy good in game. Any font is better than SongTi which is the default Chinese font.
