The argument between two children was written by Mencius and Lu Yu. Are they laughing at the argument between the two children?

The article "Two Children Debate on Japan" is selected from Liezi, which is said to have been written by Lieyukou, a native of Zheng during the Warring States Period. The article makes it impossible for Confucius to judge who is right or wrong by arguing with two children, which shows that the universe is big and the knowledge is wide, and no matter how clever a person is, it is impossible to know everything. Confucius did not "know what he knows", but adopted a realistic attitude of "knowing what he knows, not knowing what he doesn't know", thus reflecting Confucius' modest and prudent scientific attitude.
