反蹙（上府遠反不順切韻覆也從又厂聲又音手反音罕下[(巨-匚)*(十/十)]育反就也二手中指蹙上節如寶形印法也說文從戚足聲也經文或從就作蹵本字也）。

反蹙 (The first character has the fanqie fu + yuan, meaning not following; the Qieyun says: “To overturn.” It is composed of you (又) with han as phonetic. You has the fanqie shou + fan; fan is pronounced han. The second character has the fanqie [… ] + yu, meaning to approach. In the mudrā method, the middle fingers of both hands are pressed together (cu) at the upper joints to form a jewel shape. The Shuowen says: “Composed of the foot radical (足) with qi as phonetic.” In the scripture text it is also written with jiu as 蹵, which is the original character.)
