What does it mean for monkeys to climb trees to tell fortune?

Life is like a monkey climbing a tree.

Higher and higher. According to the website of personal library, it is from Tang Datian's "First". He feels like a monkey climbing a tree sometimes. Looking down, he is smiling. Looking up, his ass is his eyes and ears. If he wants to stay in this tree and not be kicked off, if he wants to see less ass and more smiling faces, he has to keep climbing, hoping to climb higher. So life is like a monkey climbing a tree, and its meaning is getting higher and higher.
