What is the earliest ink mark about the actual Zhangcao in the preservation era?

"Ping Fu Tie" is the earliest ink about real Cao Zhang in the preservation era. Details are as follows:

1. Introduction: Ping Fu Tie is a cursive work created by Lu Ji, a writer and calligrapher in Jin Dynasty. Now it is collected in the Palace Museum in Beijing. "Ping Fu Tie" has nine lines and 84 words. It's a letter from Lu Ji to a friend who is terminally ill and can't recover. It is named after the word "I am afraid it will be difficult to calm down". It was written on hemp paper by the author with a bald pen, with euphemistic brushwork and simple style.

2, the original text: Yan Xiansheng, it is difficult to calm down. This is my first illness, so I'm worried about more than that. This is the New Year holiday. A person's good luck is gone, and he is worried. I'm new here and can't get up. When you go back to the west, when you have a detailed dignity, you will enter a point of view. I will stick to my dreams from my physical illness. It's a little fierce, the hall is chaotic, and Wen Wen doesn't know.

3. Background: Pingfu Post was born in the Western Jin Dynasty, which is a transitional period in the history of China. Great social changes, whether civilization or literature and art, also affect the "consciousness" of calligraphy. Therefore, the birth of Ping Fu Tie is the product of social literature consciousness.

4, art appreciation: "Ping Fu Tie" is slender, simple and straightforward, sloppy and unconventional. It's a bit risky to be evasive. The last stroke of many words is also pulled down, which turns Cao Zhang's horizontal stroke into a vertical stroke, and the state of the words also changes according to the situation.

5. Features: Cao Zhang originated from the disintegration of official script, so it has the characteristics of official script, that is, there are obvious waves. By the end of the Han Dynasty, some calligraphers had creatively developed this kind of glyph. For example, the characters in Wei Guan Cao Shu are mostly vertical, and Lu Ji's Ping Fu Tie is influenced by it, which obviously adopts this tendency in the form of words.
