You can use acrylics on Xuan paper too, I have done it myself; but i use a lot of water along with acrylics as applying them straight from the tube gives the paint a 3D look in comparison.
But natural pigments work best and watercolors too, due to the way Xuan paper is made
however, use a normal brush when you do so, don’t use any of the traditional brushes as acrylics are made from chemicals and would ruin the natural hair used in the brushes.
