那伽龙女

The Dragon Girl or the Naga Dragon Girl (Sanskrit: nāga-kanya) was originally the third daughter of the Eastsea Dragon King, called the Dragon Girl; also a threatened servant of the Guanyin Bodhisattva, juxtaposed with the Jade Maiden on both sides of the Bodhisattva. 
龙女或那伽龙女（梵语：nāga-kanya），原是娑竭罗龙王的三女儿，叫善女龙王；也是观世音菩萨的胁侍，与善才童子并列于菩萨两侧。
