Wet mahogany hairpins are made of wet wood. Peach wood is delicate and fragrant. Peach wood itself is corrosion-resistant, wear-resistant, delicate, high in oil content, slightly transparent after fine grinding, and can restore luster after wiping with water, which is more suitable for making hair sticks. Without a gorgeous appearance, the mahogany hairpin is made of wet wood, which is easy to carve without cracking, easy to handle, but easy to deform. Dry wood is just the opposite, but it can also be repaired.

Peach trees play an extremely important role in China's folk culture and beliefs. Peach wood, also known as "dragon wood" and "ghost wood", is the most widely used material for exorcism and ghost control. Legend has it that Kuafu chased the sun and threw Shenmu into a peach garden before he died. The earliest Spring Festival couplets in China were all made of red boards, also called Taofu. For thousands of years, redwood is said to ward off evil spirits and is called Shenmu.
