According to Jiyun (Jíyùn) and Yunhui (Yùnhuì), it is pronounced “yī rèn qiè”. According to Zhengyun (Zhèngyùn), it is pronounced “yī rèn qiè”. Its pronunciation is similar to the departing tone of the character “因” (yīn). According to Shuowen Jiezi (Shuōwén Jiězì), it refers to a credential held by those in authority. The character form is composed of “爪” (claw/hand) and “卪” (tally). “卪” symbolizes the shape of two halves of a tally fitting together. It is now written as “卩”, representing a tally as a token of trust. The “爪” signifies a hand holding a seal. This is an associative compound character. Guangyun (Guǎngyùn) states: A tally is an印 (yìn). An 印 (yìn) is a token of trust, and also signifies reliance, or mutual reliance and delivery when sealing packages. Zengyun (Zēngyùn) explains: It is a token of trust inscribed with characters, used for verification.
