The eight-legged essay (Chinese: 八股文; pinyin: bāgǔwén) was a style of essay writing that had to be mastered to pass the imperial examinations during the Ming and Qing Dynasties. It is named so because it was divided into eight sections.
Structure and content 
The eight-legged essay was formulated around a rigid, artificial structure. It tested, among other things, the examinees' knowledge of the Four Books and Five Classics and ability to insert classical allusions and idioms at the places deemed appropriate. The structure of much of the essay included heavy parallelism and redundancy, rhetorical features that survive in modern Chinese expository writing.
The eight "legs" or sections were as follows:
|Opening||破題 pòtí "break topic"||Two sentences of prose whose function is to broach the topic.|
|Amplification||承題 chéngtí "carry topic"||Five sentences of prose, elaborating upon and clarifying the theme.|
|Preliminary exposition||起講 qǐjiǎng "begin speak"||Prose text|
|Initial argument||起股 qǐgǔ "begin section"||A specified number (4, 5, 8 or 9) of sentence pairs written in parallel, developing the initial argument. The parallel sentences address the topic and convey similar meanings, with similar structure but different words.|
|Central argument||中股zhōnggǔ "middle portion"||Sentences written in parallel, with no limit as to their number, in which the central points of the essay are expounded freely.|
|Latter argument||後股 hòugǔ "after portion"||Sentences written in parallel, with no limit as to their number. Here, points not addressed in the previous section are discussed; otherwise, the writer may continue padding the ideas in the central argument. It is to be written in a serious tone rooted in realism.|
|Final argument||束股 shùgǔ "tying-up section"||Parallel sentence groups, each one consisting of either two to three, or else four to five, lines. Here, the main theme is revisited and loose ends are tied up.|
|Conclusion||大結 dàjié "big knot"||Prose text where free expression and creativity are allowed. The concluding remarks are made here.|
In addition to the rules governing the number of sentences for a particular section, there were also strict limits on the total number of words in the essay. Certain offensive words and words prone to reveal the candidate’s identity or status were also to be avoided.
Words, phraseology, or references to events that occurred after the death of Mencius in 298 BC were not allowed, since the essay was supposed to explain a quote from one of the Confucian classics by "speaking for the sage"; and Confucius or his disciples could not have referred to events that occurred after their deaths.
The eight-legged essay format was invented by the Song Dynasty reformer Wang Anshi. However, it is not certain exactly when the form became the standard for the civil service examinations. A model form for essay writing issued by Emperor Taizu of Ming in 1370 is much less rigid and precise than eight-legged essays eventually became. It specifies only the topics to be tested in the examinations and the minimum length of the candidates' essays. According to Gu Yanwu, the form of the essay became more standardized during the 15th century. The term "eight-legged essay" first appeared during the period from 1465 to 1487, and the essay form was first required in the examinations of 1487 and 1496.
Since mastery of the form was a requirement for success in the examinations, commercial printers during the Ming Dynasty began to print successful examination essays as guides for aspiring candidates. The first of these appeared in pirated form during the 16th century. However, the practice gained official approval in 1587, when the government suggested that the best papers of the previous century be reprinted as examples.
The eight-legged essay was praised by some and was maintained as an integral part of the examination tradition. This is illustrated by an attempt to abolish it during the Qing Dynasty. The government at that time viewed Wang Anshi as having been a bad official. For this reason, an attempt was made in 1663 to abolish the form. However, the weight of tradition made such a change impossible. Candidates in the examinations had been trained in the form, and abolishing it threatened their livelihoods. Examiners could also mark papers written in the form in a uniform manner. Supporters of the form also argued that only the truly skilled could write eight-legged essays of high quality, so the form assisted in seeking out talent. For these reasons, the attempted change did not last, and the form was reintroduced in 1668. Yuan Hung-tao (1568–1610) praised the form effusively: "Its style is unprecedented; its diction reaches the limits of a talented writer; its tune changes with the passage of years and months. [Every writer] is able to demonstrate his unique talent with different techniques". He later declared that "the variety and liveliness of the eight-legged essay is a hundred times more than that of poetry."
In contrast, the eight-legged format is "generally considered pedantic and trite by modern-day scholars", and it had its critics during the time of its dominance as well. As early as the 17th century, the form's adoption was blamed for the decline of classical poetry and prose during the Ming Dynasty. The critic Wu Qiao wrote that "people exhausted themselves on the eight-legged essay, and poetry was only composed with their spare energy". Writing at the same time, the political theorist and philosopher Huang Zongxi echoed these sentiments. Its use has been criticized as the reason that many successful examination candidates later found themselves unprepared for the more practical requirements of government positions. In his unfinished autobiography, Chen Duxiu, the co-founder of the Chinese Communist Party, called the form "lifeless".
