From a professional point of view, it is difficult to answer such a question. Art is not a competitive sport. Since ancient times, literature has never been the best. Different people have different opinions, haha! However, we can look at it from some perspectives. For example, Pang Zhonghua, Sima and his son, Tian Yingzhang, etc. are all big names in copybook publishing. However, you must know that the large number of copybooks does not represent the high level of their hard-pen calligraphy art. Tian Yingzhang (running script, regular script), Lu Zhongnan (regular script), Wu Yusheng (running script), etc. are among them who write very well and have a good level of calligraphy art. They are available for reference! In addition: Chinese hard-tipped calligraphy online website - "Excerpts from the Calligraphy Forum" The selections in the "English" column (/) are basically good and comprehensive!
