Introduction to the plaque "Miao Yi Tong Yuan": The plaque "Miao Yi Tong Yuan" hangs under the eaves of Sanqing Palace. It was originally written by Jin Zhijun with vigorous writing. However, after being exposed to the sun and rain for a long time, the font has become old and eroded, and it is in urgent need of re-copying. However, the word "一" on the plaque has no traces at all, making it difficult to copy. Many celebrities wrote for it, but the results were not satisfactory. Suddenly a countryman came and recommended himself. After trying his writing, he was really satisfied.
