Seek a good hard pen, Copybook for calligraphy.
Hard pen calligraphy is practical. I personally recommend practicing regular script in Tian Yingzhang, Lu Zhongnan, Gu Zhongan and Qian Peiyun. Running script exercises were inherited by,,, Shen Genhong and Gao. All of the above are well known. Their calligraphy is well-behaved, full of the flavor of the times without losing the beauty of tradition. At present, the authors of many copybooks in the hard-pen book industry are commercially packaged. At first glance, their names are not small, but their handwriting is average. The authors recommended above can look at their works online. They definitely have skills.
