Why is it a compliment or irony to call Prime Minister Zhang the king of cursive script?

This is a very ironic name, because the cursive script written by Prime Minister Zhang does not conform to the calligraphy norms, and the most ridiculous thing is that he doesn't know himself, so people later laughed at him and gave him such a nickname. The explanation is as follows:

First of all, the related story is as follows:

Zhang Ai, the prime minister, writes cursive script, but he doesn't study hard. At that time, people laughed at him, and the prime minister was very calm about it. Once, when he got a good sentence, he picked up a pen and wrote it down quickly, and the whole paper danced. He asked his nephew to copy it down. When he reached the grotesque place in calligraphy, the nephew stopped blankly, took the paper he had written and asked him, "What is this word?" The prime minister looked at him carefully for a long time, but didn't know him, so he blamed his nephew and said, "Why didn't you ask earlier? I forgot what I wrote. "

Second, the protagonist of this story is briefly introduced as follows:

Zhang Shangying was born in 1043 and died in 1 12 1 year. He was born in Zhoushu Xinjin in the Northern Song Dynasty. Tianjiao is a word, and there are countless laymen. I have been charming since I was a child, and I recite thousands of words every day. When I was just working as a master book in Tongzhou, I entered the temple one day and saw the neat frontage of the Tripitaka. I said angrily, "My Confucius book is not as good as this!" " I longed for the theory that there is no Buddha. Later, I read the Vimalakīrti Sutra, and I was deeply touched by the fact that "there is no big disease and no distance", so I converted to Buddhism.

Third, the revelation of this story is explained as follows:

1. Don't just blame others for the mistake;

2. Efforts are expensive and will come in handy at critical times;

3. No matter what you do, you should do it with meticulous attitude;

4. When you hear other people's criticism, you should accept it modestly and correct it.
