A humorous novel. Old Zhang's retirement begins with an enamel mug.
It cost 8.9 yuan on Pinduoduo. White with a blue rim, it has the four red characters "Labor Is Honorable" printed on it. The reason he bought it was simple: he had 13.5 yuan left in his account and wanted to reach 20 yuan to cash out.
Who knew that buying it would drag him into a strange world?
