Hairpin is a kind of jewelry worn by ancient Han women, which is made by crossing two hairpins. The shape is that two lines are finally mixed into one, and there must be a tassel pendant at the end of the jewelry to set off. Classification includes: gold hairpin, jade hairpin, treasure hairpin, skirt hairpin (formerly known as women, also known as "hairpin skirt") and so on. It is different from another kind of jewelry with two hairpins. The connotation of jade is that the word "jade" started from the oldest writing in China and was written in Oracle Bone Inscriptions and Zhong Dingwen in Shang Dynasty. Chinese characters have created nearly 500 words from jade, and there are countless words composed of jade. The treasures in Chinese characters are all related to jade. The word "treasure" handed down from later generations is a combination of "jade" and "home", because "jade" is privately owned, so it shows its irreplaceable value. The word "jade" was a beautiful and noble word in the eyes of the ancients. In ancient poetry, jade is often used to compare and describe all beautiful people or things.
