If it is my first time to draw a folding fan, I'm afraid I won't feel uncomfortable because I don't have specific practical experience in this field, because the level of what I draw is far from that of what I draw on flat rice paper. After many times of practice and familiarity with the master method, you can naturally draw and write directly on the glued folding fan.
After being mounted, the rice paper used to make the fan should be treated with alum and then cut into the fan, so that the ink leakage and color leakage can be strictly prevented when writing and painting the fan. Therefore, when painting and calligraphy on the fan, don't use alum to treat the fan.
