In the "Jiyun" (集韵), this character is the same as the character "diàn" (钿). The "Book of Jin: Treatise on Official Dress" (Jinshu: Yufu Zhi) records: Noblewomen's Taiping buns were adorned with seven "lián" (䥖), princesses and consorts with five "lián" (䥖), and secondary wives with three "lián" (䥖). For a detailed explanation, please refer to the annotation for the character "diàn" (钿) previously.
