Does anyone know the possible story behind
this embroidered image? It is hand-stitched on
a satin pillow.

Note: thanks for your comments. Wei says this person is
a character in a famous novel,
— “Sha Monk, one of the monks in the novel "Journey to the West.”
Journey to the West is one of four of China's
great masterpiece novels of the Ming Dynasty.
The author of the novel lived
approximately 1500-1583.”
