First, writing is too slow. When the pen stays on the paper for a long time, the water will concentrate in one place. But this is normal! Just practicing calligraphy advocates writing slowly to exercise your strength. If you write too much, the speed will naturally increase, but not too fast. After all, it is regular script.
Second, there may be too much water, so we must control it.
Third, the problem of paper. Xuan paper has raw and cooked propaganda. Familiar propaganda is generally not good. Of course, it is best to use raw materials for calligraphy. There are both inferior and good raw materials, but they are not necessarily inferior. So it may have something to do with rice paper. You can try to buy other brands.
Fourth, it is ink. Better get a cupboard. The ink is thick. You may need to add water when you use it, otherwise it is banana ink. Other brands are thin and can be used directly, but there may be a little moisture when used on rice paper. It is suggested to change it to "Yidege" to control water by yourself.
