"Fu" is one of the traditional main categories of Classical Chinese poetry, or literature; however, it is traditionally not generally considered not to be a pure form of poetry (having been usually classified as "wen" rather than "shi"—however the Chinese terms do not really correspond with the English terms "literature" and "poetry").The main characteristics of the "fu" form are that each individual piece be multisectional, that the sectional divisions are marked in one or more of 3 ways, that the whole piece be monothematic (devoted to 1 explicit topic), and that the description of this topic be exhaustive, both in detail and vocabulary.
