Emperor Ming of Wei got up from the palace and wanted to install the announcement, so he asked General Zhong to climb up the ladder and inscribe it. As soon as he got down, his head and temples were bright. However, because he ordered his descendants: "Don't study calligraphy again."" An annotation of Wei Heng's "Si Ti Shu Shi" said: "(Wei) Dan was good at regular script, and the Ming Emperor established Lingxiao Temple in Wei Gongguan, but he nailed it first. The list is in a cage, and the windlass is pulled up with a long rope, and the messenger goes to the ground twenty-five feet away, and the birth is very dangerous. It is a warning to the descendants, and the family order is written. "
Usage: Wei Dan, courtesy name Zhongjiang, was good at calligraphy. Emperor Wei Ming asked him to inscribe palace plaques on high places. After he came down, his hair on the temples became white. Later, he used this code to describe his exquisite calligraphy and his reputation.
