The Afterthought, You learn something new every day, or something

You learn something new every day, or something

I just came across this entry in the Taiwanese MOE’s dictionary (教育部重編國語辭典修訂本):

彳亍

注音一式ㄔˋ　ㄔㄨˋ

漢語拼音 chìchù

彳，左步。亍，右步。彳亍指緩步慢行。文選˙潘岳˙射雉賦：「彳亍中輟，馥焉中鏑。」唐˙柳宗元˙答周君巢餌藥久壽書：「彳亍而無所趨，拳拘而不能肆。」

So, the character 行 (xíng — “go”) is made up of these two, meaning “left step” and “right step”, respectively. How about that.
