《孔子家语·五仪解》
孔子说： 从前，殷纣王时代，在国都的城墙边，有一只小鸟生出一只大鸟，占卜者说： 凡是以小生大，国家必将成为霸主，声名必将大振。 
孔子曰： 昔者殷王帝辛之世，有雀生大鸟于城隅焉。占之曰： 凡以小生大，则国家必王而名益昌。 
Confucius said: In the past, during the time of King Zhou of Yin, a small bird gave birth to a large bird on the city wall of the capital. The diviner said: "If a small bird gives birth to a large bird, the country will surely become a hegemon and its reputation will surely be greatly enhanced."
