Left part of a set of two Door Gods posters titled "Heroic figures, come back to look at the present" (英雄人物，还看今朝). The companion piece: BG D91/109.
The set refers to the folk tale "The Cowherd and the Weaver Girl". In this story, Niulang and Zhinü were gods, whose love was forbidden by celestial laws. Niulang is reincarnated into a poor cowherd on earth, Zhinü is forced to weave colorful clouds all day long in heaven.
