What does Xingwu’s approval of calligraphy and painting seals mean? There is a rubbing of the inscription on the stele, with this inscribed seal seal stamped on it.

The "Xingwu Approved Calligraphy and Painting Seal" is a special seal for the appreciation and collection of calligraphy and painting by Mr. Yang Shoujing in the late Qing Dynasty and the early Republic of China. Stamping this seal means that Yang Shoujing has seen or collected this work.

Yang Shoujing, (1839-1915), a native of Yidu, Hubei Province, was named Kaike, with the courtesy name Yunpeng, and his nickname Xinwu; his name was Kai, and later his name was changed to Shoujing, with the courtesy name Pengyun, and his nickname Xingwu ( Also known as Xingwu), in his later years, he stayed with the old man Su nearby. He was an epigrapher, historical geographer, bibliographer, calligrapher, bibliophile and numismatist in the late Qing Dynasty and the early Republic of China.

Hope this helps.
