If your handwriting is exactly the same as the copybook, you can only copy the original post, but it is actually impossible to achieve the same horizontal. The purpose of posting is to learn the strokes of words on calligraphy posts and master the strokes. The task of posting is over, and the next step is to "understand". The purpose of understanding is to prepare for integration into one's own personality. For example, the theme is Cao Quanbei in the Han Dynasty. If you bring Cao Quanbei to a certain extent, you can incorporate your own things on the basis of Cao Quanbei, but the purity of Cao Quanbei's writing and writing rules must reach more than 60%! The calligraphy works created in this way, after being seen by the Fang family, will think that you have borrowed from it, and have your own things on the basis of it, forming your own calligraphy style. If you can really reach this level, then you have succeeded!
The most terrible thing is that some people don't go deep into their posts at all, or just come to two or three points to find a shortcut to creation, and the result is self-deception. Some people stick to their posts, but find reasons to say that they are "intentionally close." This attitude of learning books is self-deception!
Pro-post is to correct your writing habits, make your writing habits close to the law post, and make your own words close to the law post, laying the foundation for future calligraphy creation. Writing is exactly the same as the words on the copybook, which no one can do unless you are a "god man". The so-called "god man" has never existed since ancient times.
