     One day when some government officials were rebuilding a house, they found a mouse hole in a corner

and used smoke to make the mice inside the hole come out. A while later they saw mice running out, one

after another, but they saw two mice didn't run away immediately. It seemed that one was trying to bite (咬)

the tail of the other.

    Everyone was puzzled, so they came nearer to take a look. They realized that one of the two mice was

blind, and the other was trying to allow the blind mouse to bite his tail in order to pull the blind one with him

to run away.

    During the meal time, they started to talk about the two mice. One serious American said, "I think the

relationship between those two mice was that of king and guard."

    A smart Frenchman said,"I think the relationship between them was that of husband and wife."

    A Japanese said, "I think the relationship between them was that of mother and son."

    At that moment, one Chinese asked, "Why did those two mice have a certain relationship?"

    Suddenly, they looked back at the Chinese. The American, the Frenchman and the Japanese who had

spoken earlier all lowered (低下) their heads in shame, and didn't answer.

    In fact, the great love is not built on friendship or blood relationship. Instead, it is based on no relationship.
