The sculptures of whose armies is Yuan Zhongyi famous for preserving?

Zhongyuan Yinyun Zhongyuan Yinyun (), literally meaning "Rhymes of the central plain", is a rime book from the Yuan dynasty compiled by Zhou Deqing (周德清) in 1324. An important work for the study of historical Chinese phonology, it testifies many phonological changes from Middle Chinese to Old Mandarin, such as the reduction and disappearance of final stop consonants and the reorganization of the tones. Though often termed a "rime dictionary", the work does not provide meanings for its entries.
