Meng Huo was popularly regarded as a local leader representing the gentries of the Nanzhong region during the Three Kingdoms era of Chinese history. When the emperor of Shu Han, Liu Bei, died, the local people of Nanzhong severed their ties with Shu Han, stating that there were three lords claiming to be the legitimate ruler of China and they "no longer knew whom should they pledge allegiance to". In retaliation, Shu Han's chancellor, Zhuge Liang, launched a full invasion on the Nanzhong region, and successfully quelled the uprising. It was recorded in the Spring and Autumn Annal of Han and Jin Dynasty (漢晉春秋) and the Chronicles of Huayang that Zhuge had captured and let go of the local leader seven times, so the leader finally swore his allegiance to Shu Han.
The popular image of Meng Huo follows Luo Guanzhong's semi-fictitious novel Romance of the Three Kingdoms, where he is portrayed as a southern barbarian tribal leader. In the novel Meng Huo was married to a fictional Lady Zhurong, who claimed descent from the Chinese god of fire, Zhu Rong.
