How to make calligraphy more flexible and specific

Can I have a look at Yan Di Xing Shu? Don't deliberately emphasize the horizontal fineness and vertical coarseness in Sacrifice for Nephew, Contention for Seats, Sacrifice for Uncle and Twelve Meanings of Zhang Changshi's Writing Style? In fact, Yan Zi has already written it? Very flexible, right? Pay attention to the concession of words? Feel the brushwork and gestures of these words with your heart? Almost none of the words in the classic inscriptions are completely stable, neat and honest. Don't write these words in print. That kind of character is very practical, but it has deviated from the true nature of calligraphy.
