《列子·力命》
眠娗、諈诿、勇敢、怯疑四个人在世上互相交朋友，各随自己的意志，整年不互相批评启发，自以为行为没有一点差错。
眠娗、諈诿、勇敢、怯疑四人相与游于世，胥如志也；穷年不相谪发，自以行无戾也。
Mianxu, Xiewei, Yonggan, and Qieyi, four men in the world, made friends with each other, each following his own will, and did not criticize and inspire each other for a whole year, thinking themselves to be flawless in their behavior.
