《魏书·列传·卷十五》
子弼推辞说： 先臣穆观以来，数代蒙受恩惠，近来检校众人，实在为之惭愧委屈。 
弼辞曰： 先臣以来，蒙恩累世，比校徒流，实用惭屈。 
Zi Bi declined the offer, saying: "Since my late ancestor Mu Guan, there have been several generations of our family who have received imperial favors. I am now only a probationary officer, and it would be a shame if I were to hold a higher position."
