Romance of the Three Kingdoms
The novel has Wu Guotai and her sister share the name "Lady Wu". She first appears near the end of Chapter 43 where Sun Quan contemplates on whether to resist Cao Cao or not. Hearing his concerns, she reminded him of his mother's dying words, "For internal matters consult Zhang Zhao; for external policy Zhou Yu." This convinced Sun Quan to discuss the matter with Zhou Yu, setting the stage for the Battle of Chibi against Cao Cao's naval fleet.

Lady Wu becomes a more prominent character during Liu Bei's time in the Southlands. When Sun Quan sought to entrap Liu Bei under the guise of proposing marriage between him and his sister, it was natural that Lady Wu would be kept in the dark on this matter. Once news of the wedding arrangement broke out, the bewildered matron upbraided Sun Quan and Zhou Yu for their duplicity. She warmly accepted Liu Bei upon meeting him at the Sweet Dew Temple while threatening those who would dare to harm him. In Chapter 55, she gave the couple permission to leave the lands of Wu in order to pay respects to her son-in-law's ancestors.

When Lady Wu reprimanded Sun Quan once more for plotting Liu Bei's downfall, Zhang Zhao had a forged letter under her name sent to Lady Sun. The contents of the letter fooled Lady Sun into thinking her mother was gravely ill, thus persuading her to go visit Wu together with Liu Shan. While Sun Quan's tacticians had hoped to use Liu Bei's child as a bartering chip for Jing Province, only Lady Sun returned due to Zhao Yun and Zhang Fei's timely intervention.
