Deliberately put two opposing and relative things or two opposing and relative aspects of the same thing together and describe and explain them in a comparative way. This rhetorical method is called contrast. Using contrast, we can reveal the opposition between good and bad, good and evil, beauty and ugliness, which gives people a deep impression and enlightenment.
Comparison mainly includes the following categories:
1. Comparison of two different themes. For example, the lyrics of "Battle Hymn of Heroes" say: the enemy decays into dirt, and the warrior turns into Venus. There is a strong contrast between talking about the enemy and talking about us. There is also Mao Zedong's famous sentence: Modesty makes people progress, while pride makes people lag behind.
2. Comparison of two aspects of a theme. A typical example is Lu Xun's famous saying: Look at a thousand fingers coldly and bow your head as a willing ox. Let's talk about a typical famous sentence, which is a famous sentence in Fan Zhongyan's "The Story of Yueyang Tower": Worry about the world first, and then enjoy the world.
3. The contrast between two subjects in one thing. Typical examples: Gladiators stop cars, shake trees, and greedy snakes swallow elephants.
