Will a Creature's Children Care for It When It Is Old and Lacks Survival Ability?
We have many animal species on Earth. Humans are actually a higher order of mammals. Most animals don’t show signs of reciprocation, and we call this “supporting parents.” Let’s analyze this with a few examples.

Humans
As the highest intelligent rulers on Earth, humans, of course, should lead by example. When our parents grow old, we should all, as children, support our parents. That's how we think and how we act, so we are the most filial higher order mammals on Earth. Without a doubt.
Crows
We've also heard from elders that crows have a ‘reciprocity’ phenomenon: older crows can no longer fly, and their young crows will bring them food. This is what we call ‘supporting aging parents.’ Crows are actually very smart; we all learned an article called ‘The Crow and the Water,’ and everyone remembers it, which demonstrates their intelligence, isn’t it because of this intelligence that they feel the need to support their aging parents? Sometimes, it's just good to do something, without needing to ask why.

Other animals that don’t support their parents, we don’t talk about them, because there are many complex situations in the animal kingdom, such as some animals leave their parents to survive after growing up and will never meet again. After all, the animal kingdom cannot be compared to human civilization. The point is: we all will grow old one day… Filial piety is first among all good things; without a doubt.
