Maoming 12 donkey friends help the elderly collect rice on their way back. What's the point of them doing this?

Maoming 12 donkey friend, on the way back, helping the elderly to collect rice is an act of helping others. They may also think that the old man can't finish the rice by himself, and then he is in a hurry, and then he just helps. This is also a life experience for myself and has made some contributions to society!
