What does the death of a fortune-telling unicorn mean?

What does "send unicorns to old age" mean?

The content is as follows.

Kirin is a god beast, and it will bring good luck wherever it goes. When you are old, you will leave peacefully without pain.

Or it also means the son of Kirin. Seeing that all the children and grandchildren are satisfied, it is natural to die satisfied and peacefully. Having a son in his later years is not very convincing.

Many times, it depends on the context,' sudden wind, a unicorn from heaven sends the old'. I don't think this means Kirin, but a gift!

"Kirin gives birth" is a myth and legend in ancient China. The meaning of this sentence is that God will give (the person who has mastered the language) a son to die of old age.
