Self-admission cursive translation of classical Chinese

prime minister Zhang likes to write cursive script (cursive script), but it is very untidy. People laughed at him, but he didn't think so. Once, he suddenly got a good sentence, and quickly asked for pen and ink to write a book. The words were very scribbled, and he wrote all over the paper. He immediately asked his nephew to transcribe the poem. My nephew was puzzled by the twists and turns of the strokes, so he stopped writing and asked Prime Minister Zhang what to read. After careful identification for a long time, Prime Minister Zhang didn't recognize what he wrote, so he scolded his nephew and said, "Why didn't you ask me earlier, so that I forgot what I wrote."
