I am a beginner in calligraphy. After using the brush, should I put the nib away or spread it out? Which preservation method is better?

It is best to hang it up, so as to prevent water from accumulating at the root of the pen or even pouring back into the pen container, which will have a serious impact on the root of the brush over time and easily make this part loose and fall off. As for the pen tip diffusion, be sure to wash the pen clean, and try not to squeeze the pen tip or dry it hard after washing. Simply wipe off the excess water in the pen tube with absorbent paper or soft towel, and hang it in a ventilated place to let the pen tip spread naturally without damaging the hair.
