Who knows what "monkeys move corn" means?

This is the monkey picking corn from the corn stalk. Baogu means corn in Chongqing dialect. Its allusion is that a monkey saw corn and watermelon while walking, so he threw corn to pick watermelon. When he met a rabbit and lost his watermelon to chase it, the rabbit ran away and got nothing. This means he can't grasp what he has, or he doesn't know how to cherish it. What he finally got was lost.
