Horace believes that the task of poetry is to inherit the will of God and guide life. Fiction is allowed when imitating nature, but it should be reasonable and close to reality. The purpose of the novel is to make people happy and entertain, not only to convince the reader, but also to make him like it, so as to achieve expectations. Poets should play with Greek examples day and night, look for real models in life and customs, absorb the language faithful to life, discover the types and commonalities of characters, and create some words with the characteristics of the times. These words can follow the traditional theme and describe people who tend to stereotype.

In addition, Horace also believes that genius can't focus on feelings, and judgment (rational judgment) is the beginning and source of writing success. Only in this way can the drama produce wonderful ideas that the audience can't put it down and linger. Horace's works: Poetry works include 2 volumes of satire, 4 volumes of long and short sentences, 4 volumes of songs, 2 volumes of songs of the century and letters. Satire and short sentences are both early works, which may have been written at the same time.

Horace claimed to have inherited the tradition of Roman satirical poems, but his satirical poems lacked political color, mainly advocated morality, mocked meanness, greed, fraud, lewdness and other bad habits in the form of small talk, and advocated the doctrine of the mean and reasonable enjoyment. Long and short sentences are a kind of two-line poems whose second line is one step less than the first line, which embodies a certain Republican tendency in content.

The first three volumes of Song were published in 23 BC, with a total of 88 songs, most of which were lyric poems describing love, friendship, wine and music. The first to sixth songs in the third volume are also called Roman Odes, praising Augustus and the revival of Rome under his rule, with elegant and solemn style. The themes of many poems in songji are similar to satirical poems, and they all advocate the ideal of staying away from worldly troubles and keeping inner peace and contentment.
