Swallow knows the next sentence.

Swallow knows that the next sentence is Kunpeng's anti-laughing pigeon. Swallows know the ambition of swans, while Kunpeng laughs at Sima Qian's Chen She Pigeon Talk. How do swallows and sparrows know the ambition of geese and swans? Kunpeng actually joked that pigeons have no ambition. Swallow knows the ambition of a swan, and Kun Peng laughs at pigeons to educate people not to confine themselves to their own activities, not to judge others by their own standards, to broaden their horizons and to be ambitious. Sima Qian was a great historian, writer and thinker in the Western Han Dynasty in China. Stepfather Sima Tan was appointed Taishiling, and Zuo Fengyi was born in xia yang (now south of Hancheng, Shaanxi).
