Taohong (Roundworm Malnutrition) is caused by children consuming excessive sweets, greasy foods, and raw/cold items. These remain undigested in the intestines and stomach, transforming into parasites. The symptoms include a preference for sleeping face down; when treating Taohong, one may observe emaciation, erect hair, or dysentery with an enlarged abdomen.
