Romance of the Three Kingdoms
In the novel, Dong Tu Na is one of the chiefs of the “Three Ravines”. The chiefs were called into a meeting by Meng Huo and told that they would be rewarded a higher rank if they could rout the invaders. They were sent in three separate directions and each given 50,000 troops. Dong Tu Na was sent to the left. In a ploy devised by Zhuge Liang, he was captured by Zhang Ni while escaping an attack launched by Zhao Yun and Wei Yan. Dong Tu Na is treated well by his captors and is released by Zhuge Liang when he asks for his freedom.

With a force of 3,000 troops, he later volunteers to repel the encroaching forces of Ma Dai but fails. Enraged, Meng Huo accuses Dong Tu Na of sharing sympathies with Shu and nearly executes him. When other chieftains intervene, Dong Tu Na is instead punished with a hundred beatings from a staff.

Convinced by other discontent chiefs to rebel, he gathers over a hundred men to take Meng Huo's head to deliver to Zhuge Liang. The mob is stopped by Meng Huo's guards, and the Naman King is instead captured and brought before Shu's strategist. After Meng Huo's second return, Dong Tu Na is killed to prevent any possible defections.
