What do you mean, D 'Anja Xiaoji lost his property and didn't go out?

It means that the lost property is hard to find.

"Da 'anjia Xiaoji loses things and doesn't go out" is a folk superstition proverb, which means that it is difficult to find lost things in Da 'anjia and Xiaoji. "Da 'an" and "Xiaoji" are two specific dates in the lunar calendar, which are considered to be conducive to doing things smoothly and avoiding bad luck respectively. What this proverb conveys is that on these two specific dates, it is easier to find things after they are lost and waiting at home.
