Yan Zhenqing's regular script history was rated as "Yan Gu", that is to say, it was excellent in composition. As Yan's "manuscript", "Sacrificing a Nephew" unconsciously puts his calligraphy skills into paper to convey an emotion, which is difficult for beginners to understand or even see the doorway. Based on this, it is best for beginners not to learn the manuscript of offering sacrifices to nephews at once. If they don't understand, there will be serious fallacies.
Secondly, the running script is a writing style based on regular script, which requires strict structure of the font, otherwise it will become scribbled, and many so-called calligraphers can't understand what they write, which is actually the reason. If you can't practice regular script well, the running script will be difficult to understand, so that you can't understand the origin of the glyphs in the manuscript of Sacrificing a Nephew at all, and you can't even recognize the words, let alone the relationship between posture and breath. If you can't do this, you can't really learn the manuscript of offering sacrifices to your nephew.
Personal understanding, please advise.
