Tang poetry

In "jueju", the first line states the theme; the second line develops the theme; the third line offers a twist or a contrasting idea, and the last line presents a conclusion. In "sijo", the first two lines play a similar role to Chinese Tang poetry, but the third line can be considered as a combination of the third and fourth line of Chinese Tang poetry. "Sijo" first part of the third line gives a twist and the whole third line offers a conclusion.
