古书还将“遗屎”写作“遗矢”，也是出于两字读音相同c“遗矢无度”，指大便泄泻不能控制2“三遗矢”，指三次解大便。古书不写“屎”而写作“矢”，不写“尿”而写作“溺”，实际是为了避免文字的移世而求其雅洁，用上了替代字。这都属于同音假借。“矢”与“屎”@李鼎 Ancient books also “left feces” as “left vector”, but also out of two phonetic pronunciation of the same c “insignificant”, refers to stool diarrhea can not control 2 “three left vector” refers to the third solution stool. Ancient books do not write “feces” and writing “vector”, do not write “urine” and writing “drowning”, in fact, in order to avoid the passing of the text and seek its Yajie, with the substitution of words. This is all homonymic under the guise of. “Vector” and “feces” @ Li Ding
