After the Confucian scholars lose seven debates to Gongsun Ling Gong, Zifang challenges her to an eighth debate, and calls in Tianming (as Ziming) as her opponent. Tianming commences by insulting her, and then by replacing her family heirloom white horse with a black horse and demolishing her argument. Having lost the debate, Li Si and his party leave, but not before reminding the Confucians that all under the wide heaven is the king's land including its people.
