This couplet comes from a folk joke. In other words, there was once an old maid who was introduced on a blind date to show her chastity. The old virgin said first: "One shot and two eggs, 38 years without resistance." Hearing this, the old maid also said, "One door has two windows. I haven't been in for 28 years. "

Later, it was often used to ridicule, and also derived various versions that made people laugh, such as:

(1) One room and two doors, no one has lived in it for 29 years. One shot, two eggs, no war of resistance for 38 years!

(2) One gun, two bullets, twenty-one years without war. One ditch, two doors,/kloc-not in 0/8 years.
