It is because the water in the fountain of the ancient Baotu Spring is as high as tens of feet that the monument was washed several times. So in the Ming Dynasty, the Jinan government asked Hu Yongzong, the governor of Shandong Province, to write a tablet, because Hu was a native of Tianshui, Gansu Province and a provincial official of Shandong Province, and wanted to mark the name of Baotu Spring with a pen to suppress this turbulent Baotu Spring. On the Dragon Boat Festival, the magistrate set up a stone tablet engraved with Baotu Spring at the source of Baotu Spring. I soon found that two points on the word "Tu" were washed away by the empty spring water, and they all said that they rushed to Daming Lake, and one of them was left on "Ming". Therefore, the word "Tu" on the Baotuquan stone tablet is missing two points.
The word "Daming Lake" was developed from the Daming Lake Monument in Jiaqing in Qing Dynasty, which was created by a calligrapher in Dengzhou, Jiaqing in 1926. This "Muyue" is the writing method of the post, not a typo. Which writing method is the calligrapher's creative freedom. In the art of calligraphy, in order to balance the font structure or aesthetic feeling, there are often cases of adding and subtracting pens.
