稽𩠐（古文𩠜同苦禮反說文稽下首也白虎通曰所以稽𩠐至也𩠐頤至地也周禮太祝辯九拜一曰𩠜𩠐二曰頓𩠐是也）。

Bowing the head to the ground (稽𩠐: the ancient form was 𩠜; fanqie 苦 + 禮. The Shuowen jiezi says: "Ji [稽] means bowing the head low." The Baihu tong says: "The reason one bows the head low to the ground is to show utmost reverence; the forehead and head touch the ground." The Zhouli states that the Great Invoker distinguishes the nine forms of bowing, the first being the稽首 [bowing the head to the ground], and the second being the 頓首 [kowtow], which are these).
