For Americans: I'm sure you've caught the play on words, but what do they mean? Hopefully I don't need to explain "rice." "Ren" is the phonetic spelling of a Chinese character (the first one in the blog title that looks like an upside down "V"). It means "people." Thus, the title conveys both the materialistic and social aspects of Chinese culture.
For Chinese (and other non-Americans): There is an old and very famous book in the U.S. called Of Mice and Men (人鼠之间). The title of this blog sounds very similar, though it has a very different meaning. Since rice is a major food in the East and "ren" is the Chinese word for people, this title means that this blog talks about things of (relating to) China and Chinese culture.
