Does writing brush strokes before homework help children feel at ease?

Practicing brush is a good extracurricular activity, which is of great benefit to children. My little sister won an award when the school held an activity. Practicing brush calligraphy can really calm people down, but it is recommended not to practice brush calligraphy just before writing homework. Children can practice in their spare time, which is better than just practicing before writing homework. Calligraphy doesn't have to be blunt, but children can also draw with a brush, which is very edifying. Hope to adopt, thank you.
