This story is about:

Snails and cows are half brothers. Snail is the eldest brother, ox is the younger brother, but their temperament is very different: Snail is sleepy at home all day, unwilling to do anything, and simply too lazy to die; Cows love to work and die hard since childhood. Gradually, the ox was no longer willing to live with such a brother, so he changed his place to live. No one feeds snails. Hungry, I had to find some moss and tender grass to eat, but I still didn't dare to go out of the stone house, so I crawled around behind my back, shrinking into a fingernail, but it still didn't wake up.
