Hani Kezi (哈妮克孜), playing Liu Fufeng (柳扶风) in the period drama Xin Jian Cuo (心间错), wears a hairpin so long that viewers scoffed online: Did ancient women really stab that kind of ruler-length pin into their buns? Could they yank it out and use it as a dagger mid-conversation?
Yes, those long pins were real. And without them, those towering, jewel-studded coiffures in every dynasty drama would collapse into a messy pancake within minutes. The answer lies not in decoration but in engineering. Ancient long hairpins—often 20 to 30 centimeters, sometimes hitting 35—served as structural rebar for high buns and circular looped chignons. Think of them as invisible super-bobby pins that held everything from real hair to added wigs. They weren’t a Tang dynasty invention, either.
As early as the Han, long combs called zhi (擿)—with long teeth—gripped elaborate updos. In the Mawangdui (马王堆) tombs, Lady Xin Zhui (辛追) wore three zhi made of tortoiseshell, horn, and bamboo simultaneously; the longest measured 24 centimeters—roughly the length of one and a half pencils—thrust horizontally across her crown like a proud banner.
Ritual Status
Length signaled rank. The Book of Later Han – Carriage and Dress (后汉书·舆服志) decreed that grand empress dowagers and empress dowagers, when attending ancestral temple rites, must wear a tortoiseshell zhi “one chi long” (Han-era chi being about 23–24 cm). That specific material and measurement were not optional—they were diplomatic credentials pinned to the head. A woman who could sport such a heavy, long pin was a woman with political weight.
During the Tang, ladies adored towering, layered buns so massive that short pins buckled under the load. Excavated Tang tombs regularly yield pins exceeding 30 centimeters. When they added yi ji (义髻)—premade wig pieces—they had to drive these long pins straight through the fake-and-real hair sandwich to lock everything in place. Without that length, the whole construction slid sideways at the first bow.
But even long pins sometimes failed. Tang and Song women called in reinforcements: insertion combs, thick-backed, fine-toothed wedges that they jammed between the wig and natural hairline. That comb acted like a wooden dowel, gripping the false bun with brute friction—a medieval anti-slip anchor that no windy courtyard dance could shake loose.
Vertical Upgrade
Song women took the game further. Beyond the classic horizontal stab, they popularized a vertical insertion—the “cross” pinning style. The pin head was bulbous, almost spherical, and they drove it straight down into the center of the bun. This perpendicular lock created a four-way brace with horizontal pins, dramatically improving stability. Some scholars trace this technique to Song court crown-wearing customs; they simply borrowed the pinning method from formal headgear and applied it to daily buns, turning a ceremonial trick into street-level practicality.
That cross method also solved a chronic headache: heavy ornamentation. With a vertical central pin, a woman could hang more pearls, gold flowers, and kingfisher-feather trinkets without fearing a sudden avalanche. The pin became less a fastener and more a foundation pile—driven deep, it bore tension from all angles. Excavated Song tombs show paired horizontal and vertical pins still lodged in skull fragments, proving that this “crucifix” system actually worked for the deceased’s final journey, too.
Living Legacy
Did this long-pin culture vanish with the imperial era? Not at all. It survived well into modern times—and even echoes today in regions like Fujian, where the so-called “three knives” headdress once flourished. This ensemble comprised three long, blade-shaped hairpins—one vertical, two flanking sideways. Folk theories about its origin abound: some say it was a coastal defense against Japanese pirates; others trace it to the Wei-Jin “five-weapon pendant”; still others link it to She (畲) minority traditions. Whatever the root, the headdress was never purely ornamental—it was an explicit statement of self-defense, a visible armature that said, “I am not a soft target.”
Women wearing the three knives would coil a tight bun at the nape, then drive the central sharp-tipped pin from the top down, and the two side pins from left and right—all with the blades pointing outward. The side pins had rounded heads, so only the center one was truly dagger-like, but the overall silhouette screamed warning. In coastal villages, elderly women still recall grandmothers who wore these daily, not for festivals but for routine trips to the market or the fields. That practicality—protection woven into hairstyling—shows how the ancient structural logic of long pins mutated into a folk weapon, blurring the line between fashion and fortress.
Today, with women’s hairstyles simplified to bobs and ponytails, these once-indispensable long pins have retreated from daily life. We barely see them except in museums or period dramas. But next time you watch Xin Jian Cuo and smirk at that absurdly long hairpin, remember: it wasn’t absurd. It was architecture, ritual, and resistance—all pinned together with a single stroke of jadeite or nephrite. Would you wear one today? Maybe not. But would you respect the woman who could? Absolutely.
