`教养` is a cornerstone of Chinese social evaluation, deeply rooted in Confucian values. It embodies the idea that an individual is not an isolated entity but a representative of their family. Your public behavior directly reflects your family's honor and the quality of your upbringing.
`教养` is a word you'll hear frequently in daily life when people are judging others' behavior. It is almost always used in its noun form to describe a quality someone has or lacks.
