Jia Fan 賈範

Chapter 106 of the Romance introduces Gongsun Yuan as the grandson of Gongsun Du of Liaodong and the son of Gongsun Kang. In the 2nd year of Taihe (228) Gongsun Yuan seized the position of his uncle Gongsun Gong, and Cao Rui appointed him General Who Displays Valor and Administrator of Liaodong. Later, when Sun Quan sent men to enfeoff him as King of Yan, Gongsun Yuan, fearing the Central Plains, beheaded Sun Quan's two envoys and sent their heads to Cao Rui, and Cao Rui made him Grand Marshal and Duke of Lelang. Romance, Ch. 106 §1–2

Still not satisfied, Gongsun Yuan confers with his followers, styles himself King of Yan and changes the era name to the 1st year of Shaohan, and his Deputy General Jia Fan remonstrates. The Central Plains, he says, treat his lord with the rank of a supreme duke, which is neither low nor mean, so to turn against them now would truly be contrary to what is right; moreover, Sima Yi is so skilled in using troops that even Zhuge, Marquis Wu of Western Shu, could not defeat him, let alone his lord. Gongsun Yuan, in a great rage, shouts at his attendants to bind Jia Fan and is about to have him beheaded. Romance, Ch. 106 §3

Then the Army Adviser Lun Zhi says that Jia Fan's words are right and, citing the sages' saying that when a state is about to perish there are always evil portents, reports three strange events in the state: a dog wearing a headcloth and a red robe climbed onto a roof and walked about like a man; inside the rice steamer of a villager south of the city a small child was found steamed to death; and in the northern market of Xiangping the ground caved in and a lump of flesh welled up that had a complete head and face but no hands or feet. Gongsun Yuan flies into a rage, shouts at his guards to bind Lun Zhi, and has him beheaded in the marketplace together with Jia Fan; then, making the General-in-Chief Bei Yan Commander-in-Chief and Yang Zuo leader of the vanguard, he raises 150,000 troops of Liaodong and invades the Central Plains. Romance, Ch. 106 §4–5

When Sima Yi arrives with his army and besieges Xiangping, Gongsun Yuan and his son open the south gate by night and flee, but, surrounded on all sides, they dismount and surrender, and are beheaded on Sima Yi's orders. Entering Xiangping, Sima Yi kills Gongsun Yuan's clan and all the officials who took part in his plot. When someone tells him that Jia Fan and Lun Zhi had earnestly remonstrated with Gongsun Yuan that he must not rebel and were both killed by him, Sima Yi raises burial mounds over their graves and brings honor to their descendants; then he distributes the treasure in the storehouses as rewards to the three armies and returns to Luoyang.
