The silver characters, fu shou ru yi, are a wish for happiness and longevity.
Ruyi sceptres bearing the mark of Hu Wenming appear to be quite rare. One with a somewhat naturalistic rendering of the ruyi head, a twelve-character inscription inlaid in silver wire on the reverse, as well as the gilded cartouche inscribed with the six-character mark, Yunjian Hu Wenming zhi, is illustrated in Emperor, Scholar, Artisan, Monk, Sydney L. Moss Ltd., London, 1984, pp. 272-3, no. 126. The author notes that within the literati world ruyi sceptres were often presented on one's sixtieth birthday as a wish for longevity.
