Names and etymology
The Sino-Korean word chonggak+Korean word mu is a compound of chonggak and mu. In premodern Korea, unmarried men and boys pulled their hair into a long braid, while married adult men wore their hair in sangtu, a topknot. On the day of the coming of age ceremony, a boy's braid was undone and it was first made into chonggak, hornlike double topknots, before it was undone again and be made into sangtu. As the shape of chonggak radishes resembled the shape of chonggak hair, it came to be called by the name of chonggak radish.Altarimu is also a common name in Korea. One theory about the etymology of 알타리 is that it comes from 알달리 referring to the lower part of the radish, and later transformed into altari.
