 Just over 700 of his poems still exist, four of them are included in the classic Qing Dynasty anthology "Three Hundred Tang Poems", which was first published in the 18th-century.He excelled in the shorter, more complex forms of Chinese poetry.In technical terms, he preferred using heptasyllabics (seven character lines) to pentasyllabics (five character lines) (123 to 47 examples in Wu Zaiqing's edition of selected works), regulated rather than unregulated (145 to 22 examples in Wu), and short forms (8-line lüshi and 4-line jueju) to longer poems (142 to 25 examples in Wu).
