What does it mean for Copybook for calligraphy to be close to the original university? Should it be as big as the words on the original post?

This question is controversial. Some people think it is as big as the original tablet, so that we can better understand the author's brushwork, but which tablet is the original size? How many learners can ask the teacher, and how many know how big the original word is? If you don't have an accurate grasp, is it still meaningful to understand the so-called brushwork? Therefore, individuals prefer another understanding of "writing words with the same size as the copybook when studying", which is easier to understand. It is equivalent to copying the words on the copybook to the same size of writing paper, without any scaling, writing for as long as possible and writing as thick as possible. Doing so is more conducive to discovering the shortcomings in the writing process. It is an obsession to blindly pursue the size of the original flat plate.
