The cursive text in the photo reads vertically from the right:
Although the calligraphy style is different from the real regular script, cursive seal script and official script, it is generally noble, powerful, elegant and charming
The closest thing to it is the inscription and postscript written by Zhang Su in the Ming Dynasty on the "Dianzhu Mingjuan" written by Huang Tingjian, a great calligrapher in the Song Dynasty. The full text is as follows:
Although the calligraphy style has real regular script and cursive script , the difference between seal script and official script is that it is generally more valuable than strong and elegant, while charming and skillful is not so valuable. Du Shaoling said: Those who can communicate with the gods only if their books are expensive, thin and hard, have a purpose. During Yuanyou's reign, Fu Weng was the best in the world in terms of writing, and his calligraphy was outstanding in other matters. Although things are valuable based on people, Kuang Gong's writing style is ancient and unique, so trust is valuable. Someone may have something, but he still knows how valuable it is and loves it. If he is a public servant, he would rather not inherit it and keep it for the benefit of the world. In the spring of the sixth year of Jingtai in the Ming Dynasty, on the auspicious day of the third month of the third month, Gengwu Kexiang paid tribute to Zhiquan and Zhang Sushu.
Hope this helps.
