This manuscript centers on the concept of "fire," systematically dissecting the "internal heat" problem most familiar to Chinese people. It combines classic Chinese medicine texts such as the *Huangdi Neijing* and *Shanghan Zabing Lun* to interpret the physiological significance of "fire," analyzing how modern lifestyles such as stress, staying up late, and unbalanced diets can trigger "deficient fire" and "excess fire" in reality. For the four major types of excess fire—lung fire, stomach fire, heart fire, and liver fire—it details the key points for differentiating over 30 symptoms and corresponding Chinese patent medicines, and reveals common pitfalls such as misusing ginger soup in the early stages of a cold and abusing heat-clearing drugs, which can worsen loose stools. From differentiating typical symptoms like sore throat, insomnia, and bad breath, to interpreting bodily signals such as acne location and abnormal sweating, it guides readers to understand the complex essence of imbalance of Qi, blood, Yin, and Yang behind "internal heat."
