Jinniu (the year of birth and death is unknown) was originally from Qujiang, Cao Ren's department, and later became a general.

Thousands of Zhou Yu soldiers came to attack, and thousands of strikers began to come. Coss went to the city to have a look, but he recruited 300 people and sent Taurus to fight. But the other side has more troops, so Taurus is surrounded. Cao Ren personally went into battle to rescue Taurus.

Sima Yi asked Jinniu to light the bait to lure the Shu army. Just after the war, Zhuge Liang withdrew his troops and chased Qishan. Ma Dai was invaded by Shu, and Sima Yi sent the general Jinniu to repel him and beheaded thousands of soldiers. Gongsun Yuan, Sima Yishuai, Jinniu and Hu Zun set out from Luoyang and settled in Liaodong. Taurus is an official after the general.

Later, Sima Yi was afraid of design and was poisoned.
