Most of the pens used by calligraphers are light brushes and hard pens, and there are few heavy pens. The 68-pound heavy pen can still write magnificently. Looking at the whole country, Wang Huaizhong, a calligrapher with heavy brushwork, is probably the only one. As for the value of Mr. Wang's works of art, it depends on personal preference, because the domestic painting and calligraphy market does not have accurate pricing for works of art.
