Where does 丢三落四 come from?
It does not come from a specific anecdote; it is a long-established colloquial expression. It is built from two numbers (three and four) that count nothing here but evoke “a bit of everything” and so the disarray of someone who keeps leaving things behind. It already appears in the classic novel 《红楼梦》 (18th century), in chapter 67. Note: here 落 is read là (not luò), with the sense of “to leave behind or forget something”.
