Chinese Child Protection Charm Hat: "Tiger Hat" or "100 Day Hat"

A tiger hat is a traditional baby gift in China. The tiger is believed to protect the child from bad spirits and bring good luck. During the Qing dynasty and early 20th century, children's (especially boys') clothing was often decorated in auspicious creatures to protect against evil spirits that might whisk the child away. While this custom has declined in urban areas, it can still be found in more rural areas of central China.

The tiger is a popular choice because it is a divine creature in Chinese folklore. A tiger hat scares away evil spirits or fools them into thinking that the child is a fearsome animal. If the tiger hat is worn on birthdays or special occasions, it is supposed to bring luck and peace.
