The quatrains in China's metrical poems require that each poem should be flat and flat, so that the tone is cadenced, sonorous and musical. Sonnets do not require the same number of poems per line, but they require the same cadence, and each cadence has two syllables, one light and one heavy. Spencer style and Shakespeare style require five cadences and ten syllables per line. Peterak style requires 11 syllables; French requires 12 syllables.
onegin's stanza with a light tone at the end is called "Yin Yun", with nine syllables (the last light syllable does not constitute a foot); Some people who end with stress call it "Yang Yun", with 8 syllables.

the history of Chinese sonnets
during the Republic of China in China, there were also poets who wrote Chinese sonnets, such as Take Back by Wen Yiduo and The Path of Yuan Ye by Feng Zhi. The first eight lines of Take Back are divided into two sections, each with four lines, and the second half with six lines. The rhymes are "a-b-a-b, c-d-c-d, e-f-e-f-g-g", which are similar in form to English sonnets.
Although Chinese sonnets introduce western rhymes, they do not pay attention to metrical phenomena such as iambic and iambic (a small amount) in English poems. Because of the need of music harmony, the meter of sonnets is also quite strict, and the harshness of some places (such as rhyming requirements) even exceeds that of China's ancient poems.
