I am a novice. How to dip the brush in ink? How to clean it?

Adjust the amount of ink first (not too thick or too thin, you can try it on the same waste rice paper as you wrote). When writing, all pens should be dipped in ink, so that the strokes can be full, round and powerful.

After writing brush strokes, be sure to wash them with clean water. When washing, be sure to pay attention to the vertical bristles, and don't mess them up, or they will be hurt.

Both washing and rinsing are acceptable, but in the end, washing and rinsing will be the only washing methods. After washing, arrange the nib into the same shape as the new pen. Don't wear a pen cap, just hang it on the pen rack and soak it in water next time.
