Some say that the grace of raising is greater than the grace of birth, because raising a child is a very tiring task. Watching the child grow from a tiny bundle into an adult is worrisome, and this is nobler by countless measures compared to merely giving birth and not raising the child.
Some say that even raising a cat or a dog can generate affection, let alone someone you interact with day and night.
The weight of birth grace versus raising grace depends on the situation and person and cannot be generalized with one sentence.
Take Shi Guantao, does the Shi Family have the grace of raising him? Yes, but it's limited, not as big as the sky, nor as deep as the sea, and falls short of the grace of birth from Gu Daitou and Doctor Gu to him, for the latter are also victims.
Conversely, for Gu Qing, the Shi Family has the grace of birth, while the Gu Family has the grace of raising, and any normal person would say the grace of raising is greater than the grace of birth.
