匍匐（上僕逋反下朋北反毛詩箋云匍匐言盡力也顧野王云手行也說文云匍手行也匍伏地也二字並從勹甫畐皆聲音包）。

匍匐 (the first character is *pu* combined with *bu* [fanqie: pu-bu]; the second character is *peng* combined with *bei* [fanqie: peng-bei]; Mao's commentary on the Shijing says: “匍匐 speaks of exhausting one's strength.” Gu Yewang says: “Crawling on hands.” The Shuowen says: “匍 means walking on hands; [匍匐 means] prostrating on the ground.” Both characters are formed with 勹, with 甫 and 畐 as their phonetic components; 勹 is pronounced *bao*).
