I have tried to do this automatically -- most hinting maintains the
width of horiziontal amd vertical lines/strokes, slanting curved
lines tend to become out of proportion, or ugly. It is not easy.
To look nice in Chinese charcters have other rules, such certain
strokes extend to fill an empty space so there are no large gaps
inside the character, or contract to avoid touching.
Certain styles have different rules eg strokes all about the same
width (kaishu), horizontal strokes wide vertical strokes narrow (
basically songti) .
An expert calligrapher also has lots of other rules that make a
character "good" .

Nowadays many OSes have font enhancers that make bad fonts look good.
