Including Biography of Ji An, Tao Te Ching, Ten Notes of Caotang, Biography of Laozi, Jiuchenggong, etc., will have no influence on daily Chinese characters. The reason is that our daily writing speed is very fast, we use Lian Bi characters, and the initial practice of calligraphy is regular script.
Just writing regular script instead of running script will become a situation where you write carefully and look good, and when you are in a hurry, you will let yourself go. Running script is not a quick writing of regular script, nor does it have to be adhered to. It's no use insisting on writing a million words. Once the foundation is laid, writing a running script, such as a few thousand words, will greatly change the daily words.
