Huadian, also known as huazi, mianhua, meizi, plum blossom makeup or plum makeup or Shouyang makeup, is a form of traditional Chinese women ornamental forehead makeup, which is located between the eyebrows and sometimes on the cheeks, the temples, and the dimples. According to a folklore legend, the huadian in floral shape originated in the Southern dynasty period; its creation is attributed to Princess Shouyang, a daughter of Emperor Wu of Liu Song. However, the origins of the huadian can be traced back earlier than the folklore legends to the Qin and Han dynasties, and even in the pre-Qin period with its customs arising as early as the Spring and Autumn period and Warring States period based on archaeological artifacts and studies. Its origins has no connection with the diandan, i.e. Baihao, found on the middle forehead of Buddha statue. The huadian was also popular among Tang and Song dynasties' women. The popularity of the huadian declined in the Yuan dynasty. The huadian forms an integral part of Chinese clothing culture. In present days, huadian is often combined with the wearing of hanfu, the traditional clothing of the Han Chinese.
