In ancient times, an official had no children, and his wife was not even allowed to take concubines.

This was a persistent worry of his. The official had a nephew who handled minor matters.
The next day, he brought a group of workers to the official's house,
measuring land and inspecting the house, gesturing and giving directions.
The official's wife asked what was going on, and the nephew said it was nothing, since her husband had no children anyway.
From now on, all of this would be mine. Let's plan it out now,
so that later, I can leave a room for Auntie on the west side. You can rest assured.
The wife couldn't say a word and later arranged for her husband to take a concubine.
