Is there a difference between the styles of gouache in the north and the south? If you study in the north, will you get a low score in the provincial exam?

No problem. North and South painting schools are different. In gouache, the southern painting is pure in color, while the northern painting is sloppy, with clear blocks and rich colors. It depends on which province you are in and what university you want to go to. Personally, I suggest not to be bound by the North-South style. It is very important to find a painting method that suits you ... combined with the contents of the book ... a book with good teaching and perfection, including the North-South painting school.
