What do you mean, "stormy waves, my nephew failed"?

I copied it to a strange place, and my nephew had to stop because he didn't know it.

For this story, see Hui Hong's Cold Zhai Night Talk: "Prime Minister Zhang Caoshu writes well, but unfortunately he can't. At that time, all descendants laughed at him, and the prime minister was as cool as a cucumber. A word a day, a pen, a book, a piece of paper full of dragons and snakes flying, I asked my nephew to record it. When the waves were dangerous, my nephew turned a deaf ear and asked, "What's the word here?" The prime minister has been familiar with it for a long time, but he doesn't know it himself. He scolded his nephew and said,' If you hadn't asked earlier, I would have forgotten. "

Free translation:

Prime Minister Zhang (suspected to be a contemporary prime minister of Hui Hong in the Northern Song Dynasty) liked to write cursive script, but he couldn't write it properly, and people at that time laughed at him. The prime minister is as self-righteous as ever. One day, the Prime Minister had a satisfactory poem, picked up a pen and recorded it quickly. His cursive scripts are like dragonflies and snakes. Let my nephew copy it again, and copy it to a strange place. My nephew stopped because he didn't know him, picked up a piece of paper and asked the Prime Minister, "What is this word?" The prime minister looked at it carefully for a long time, but he didn't know it himself. Scold his nephew and said, "Why didn't you ask earlier?" I forgot! "

Prime Minister Zhang's nephew "turned a deaf ear", because Prime Minister Zhang's handwriting was too scribbled, he didn't know it, and he couldn't copy it, so he had to stop copying it.
