During the Taizong Dynasty, there was a writer named Wang who studied Youjun calligraphy, mastered its method, and served in the Hanlin Academy of Calligraphy. While the emperor was listening to the government, he paid attention to calligraphy and sent several servants to hold the calligraphy instructions. Every time he wrote, he thought it was not good, so Taizong deliberately studied it. Asking again, the answer is the same as before. Or he asked about his meaning and wrote: "The calligraphy is really good. If it is suddenly called good, I'm afraid the emperor will no longer use it." After that, the emperor's writing skills were exquisite, surpassing those of the ancient times, and the world thought it was the rule of writing.
