Korean crowns have been produced and developed in Korean folk life since prehistoric times, especially Hwagwan and Jokdu-ri were developed as crowns for women's hair decoration before the Three Kingdoms Period, and were handed down as relics from the Joseon Dynasty. Due to the loss of economic value, it is not easy to inherit as a single item of tubular hair, so preservation as an Intangible Cultural asset is essential in Seoul.

On November 16, 2017, the Gwanmojang was designated as Seoul Intangible Cultural Property No. 50, and Park Seong-ho was recognized as the holder of the Gwanmojang.
