Hairpin

The creation of different hairstyles, especially among women, seems to be common to all cultures and all periods and many past, and current, societies use hairpins.

The hairpin may be decorative and encrusted with jewels and ornaments, or it may be utilitarian, and designed to be almost invisible while holding a hairstyle in place.

Some hairpins are a single straight pin, but modern versions are more likely to be constructed from different lengths of wire that are bent in half with a u-shaped end and a few kinks along the two opposite portions.

In ancient China, hairpins were worn by men as well as women,[3] and they were essential items for everyday hairstyling, mainly for securing and decorating a hair bun.

When they turned fifteen, they could be considered as young women after the ceremony, and they started to style their hair as buns secured and embellished by hairpins.

If this couple were ever to get separated in the future, when they reunite, they can piece the two halves together, and the completed hairpin would serve as a proof of their identities as well as a symbol of their reunion.

In addition, a married couple is sometimes referred to as jie-fa fu-qi (Chinese: 結髮夫妻), an idiom which implies the relationship between the pair is very intimate and happy, just like how their hair has been tied together.
