What kind of brush is better for running script? Want to come to Teng Xu from Wen Huiming?

Both pen and paper should be considered. In short, a strong paper means a weak pen, and a weak pen means a strong paper. If the paper has strong water absorption, use a wool pen with weak elasticity, otherwise the paper may be broken with a wolf brush with good elasticity; If the water absorption of paper is weak, use a wolf pen with strong elasticity, otherwise the written words will float on the paper. Good luck with your work.
