Yilin Verse
言無要約，不成劵契。殷叔季姬，公孫爭之。彊入委禽，不悅於心。
Words lack binding pledge; no contract or deed is formed. The Yin lord youngest daughter and the Gongsun clan contend for her. The betrothal gifts are forced upon them; it does not please the heart.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
