Example:

Yu: I will never go to an Internet cafe! It is ironic that some students nowadays are addicted to the Internet and cannot extricate themselves, and will eventually regret it.

Flies: The world has never lacked the beauty of egg gaps. What it lacks is the eyes to discover the beauty of egg gaps.

Comment: Do you have a pair of clever eyes? Will you discover the "truth, goodness and beauty" and "falseness, evil and ugliness" of life?
