"The so-called 'five delays' refer to delays in standing, walking, teething, hair growth, and speaking. The 'five flaccidities' refer to flaccidity of the neck, mouth, hands, feet, and muscles. These occur due to innate deficiencies and inadequate nourishment of the vital essence.
"However, with the improvement of modern living conditions—which can even lead to over-nutrition—cases of the five delays and five flaccidities are gradually decreasing in clinical practice. Taking their place is an increase in children with precocious puberty. Precocious puberty is a modern medical term, but in ancient traditional Chinese medicine texts, Miaomiao's condition is known as the 'premature sprouting of Tiangui.'"
"What is Tiangui?"
