The guanli or gwallye is the coming-of-age rite, performed at about twenty for men and, in the corresponding jili, at about fifteen for women. The classical form has the initiate change headgear and dress three times, each accompanied by a spoken charge from the presiding elder, culminating in the conferral of a zi, a courtesy name, which thereafter replaces the childhood personal name in adult address — an important point, since using someone's personal name after this was a discourtesy. Zhu Xi codified the procedure in his Family Rituals in the twelfth century and that text remains the reference. The rite largely lapsed under modernisation in both China and Korea and has been revived from the late twentieth century, frequently in a civic rather than lineage form: Korea holds a national Coming-of-Age Day on the third Monday of May, and Chinese cities and schools have staged mass ceremonies for eighteen-year-olds in Han-style dress, which carries an obvious cultural-nationalist charge as well as a ritual one.
