The right part of these meaning-sound characters 形声字, 攵， is called 反文旁 fǎnwénpán. The sound part is is on the left side and the meaning part right, which is different the majority of meaning-sound characters: meaning part on the left and sound part on the right. The 反文旁 in these characters had differently been 攴 pū in archaic characher writing，regionally meaning whipping or thrashing when used as an indepent characters, and then used as a component in Characters to carry the meaning of 强制 compulsory，命令 demand，必须 obligation. All the four characters with 攵 as component had this meaning in archaic Chinese language and their writing forms.

攵is short by 攴(pu1),攴 consists by 又which means hand in ancient China，and the top of it means a stick，so 攴 means hit someone slightly by a stick. 救：means stop someone in ancient chinese 攻：means hit 敞：means make a place flat in ancient chinese（攴means hit the earth） 敬：means respect（攴means press someone in this character）
