Abstract: Bowing, kowtowing and scraping, the traditional Chinese etiquette, have gone beyond national boundary and incorporated into the world civilization. Few people, however, has traced their origin and evolution. Based on the textual criticism of the oracle bone inscription "鞠" and the research results of archaeology, folklore and philology, the essay comes to a conclusion that bowing, kowtowing and scraping are the inheritance, change and development of "Ju Ji"(an ancient Chinese religious rite offering bow-shaped sacrifices to worship heaven).
