Pronounced dīng chǒng jiā tíng, its meaning is closely related to DINK (Dual Income, No Kids), which refers to families that do not have children but raise pets in order to experience the feelings of parenting. These families treat pets as their own children and give them premium high-quality living conditions. They regard the pets as their inner sustenance.
Let's put it into context:
Phil: Do you remember Gao Feng, the tall guy with a beard and moustache that we met the other day? He has been married for eight years. But he looks like he is only 23 or 24 years old.
Allen: Oh, the Gao family. I have heard about them before. They are dīng chǒng jiā tíng. Their only "child" is the lovely dog.
Phil: Well, why don't they raise a child? I mean, a human child.
Allen: Maybe that's the lifestyle they choose. Haven't you heard about all of the DINK families these years?
