What's the difference between Jin Chai and Jin Chai?

Structurally, hairpins are single needles, while hairpins are mostly double needles (there are also three needles).

Functionally, both of them are fixed on the bun, but the hairpin with two pins or three pins is stronger than the hairpin with fixed bun.

Development history: hairpin appeared earlier and was used in Zhou Dynasty. Zan was developed on the basis of Zan and became popular after the late Western Han Dynasty.

Style: Hairpins are unisex, while men's hairpins are longer and more practical. Wood is only suitable for women.
