8-year-old children should buy that kind of brush to practice writing. Taobao has seen a lot, divided into large, medium and small. What size should I buy? You should practice that hairstyle first.

Minimum size! Because the child's fingers are also in the development stage! Too thick a pen has an impact on children's finger development! Also, if the child is in the third grade and has already started to use a pen, you can let the child learn brush calligraphy; If you are not in the third grade, don't let your children learn Chinese calligraphy first! A little advice, for reference only!
