In the *Qianjin Yifang* (Supplement to the Thousand Golden Formulas), it is recorded that the Yellow Emperor asked Qibo, saying: "There are many prescriptions for malaria, yet few cure it. Why is this?" Qibo replied: "Malaria has twelve types." The Yellow Emperor said: "Regarding the names of the 'malaria ghosts,' I wish to hear them." Qibo said: "If you obtain the name of the malaria ghost, the disease will be cured; if not, a hundred prescriptions will fail to cure it." The Yellow Emperor said: "I wish to hear about the twelve time-periods corresponding to the malaria ghosts."
