The predecessors attached great importance to writing, but they did not write in the order of "three, a hundred, a thousand", but in another way, that is, "Master Kong Yiji changed his famous articles by 3,772, and his son's son, son of his son, son of his son, son of his son, son of his son, son of his son, whose benevolence is known". There are several steps: the first step is to write big characters. First, they painted red (some people even put their wrists in front), imitated shadows, further wrote Mi Zige, and then further posted it. Write small characters only if you have a little foundation in big characters. Reading and writing are out of sync.
