Clouds and ants present the marvelous relationship between people and environment. When thinking about this, it also reflects the relationship between you and this world, you and yourself. The skeleton-like cloud on the right up corner implies the evil power from a dark world. The left part presents the against or accepted conversations with it. The laughing cloud in the middle is quietly watching this unavoidable fate game. The constantly changing shapes of the clouds are just like the uncertainties of our life. It’s also a reflection to environment, dreams, emotions, and desires. The sociable ants can work together as a group to raise an article 50 times heavier than themselves. They can cooperate so closely but can also attack each other for private benefits. These characteristics seems like the nature of human beings. Clouds should be something far away from an ant on the ground. But the conflicting and ridiculous situation that makes them strive for survival hardly, is so like our life.
