" Ancient Chinese eyebrow pencil, also known as "meidai," was an essential beauty tool for women in ancient China. Made from natural materials such as graphite, lead, and ink, meidai was used to darken and shape the eyebrows. The practice of using meidai dates back to the Tang Dynasty (618-907 AD), and it became increasingly popular throughout Chinese history. In ancient China, well-shaped eyebrows were considered a sign of beauty and sophistication, and women often used meidai to enhance their appearance. The use of meidai was also believed to have spiritual and medicinal benefits, as it was thought to ward off evil spirits and promote good health. Today, meidai is still used by some women in China, and it has become a cultural symbol of traditional Chinese beauty."
