3. Introduction to Prime Minister Zhang: Prime Minister Zhang was a famous calligrapher in the Tang Dynasty. His cursive calligraphy works were praised as "the best in the world". His cursive calligraphy is smooth, majestic, rich in poetry and artistry. "Prime Minister Zhang is good at cursive script" tells the story of Zhang Shangying, a native of the Northern Song Dynasty. Original text: Prime Minister Zhang was fond of cursive writing but not good at craftsmanship. At that time, everyone laughed at him, but the Prime Minister was very complacent. One day I got a sentence, and I wrote quickly with my pen, and the paper was full of dragons and snakes flying around. Let his nephew record it. When the wave was dangerous, my nephew stopped in confusion. He held the letter and asked, "What's the word for this?" The prime minister had seen it for a long time, but he didn't recognize it. He criticized his nephew and said, "Why didn't Hu come earlier and ask? I forgot about it."
