When Lu Xun was a child, he practiced pairing in a private school. When he learned three-character pairing, Mr. Lu gave a question, and the first part was: unicorn.

Everyone answered their own answers, but Lu Xun was right: flounder.

Mr. Listened to very appreciated, commented:

Unicorns have no numbers but show the meaning of "one" (through the word "independence"); The flounder also has no numbers, but it shows the meaning of "two" (through the word "bi", which means side by side and side by side), and it is very neat and clever.
