The ancient Chinese initial consonant of Zhi-Zhuang名hang (知莊章) group generally read as retroflex (Zhuang 莊group or read blade-alveolar) in Beijing dialect, and Shanxi Yuncheng (運城) dialect is relatively complicated. According to the distribution of the sixteen she (十六攝), there are six patterns of status in these three groups in Yuncheng (運城): (1) Zhi-Zhuang-Zhang (知莊章) pf-; (2) Zhi-Zhuang-Zhang (知莊章) ts-; (3) Zhuang (莊) pf-, Zhi-Zhang(知章)ts-; (4) Zhuang (莊)ts-, Zhi-Zhang (知章)pf-; (5) Zhuang (莊)ts-, Zhi-Zhang (知章) ts-; (6) Zhuang-Zhang (莊章)ts-, Zhi (知)ts-. The phenomena can be roughly understand from the types of Zhongyuan Yinyun (中原音韻). The pronunciation of labiodental has come from a retroflex before hekouhu (合口呼), and the pronunciation of blade-alveolar has come from a retroflex before kaikouhu (開口呼) . Both changes are representative of the First Movement.
