阿珂 is the famously beautiful female character in Jin Yong's 《
鹿鼎记》 (The Deer and the Cauldron, 1969–72) — daughter of Chen Yuanyuan and Li Zicheng, raised by the assassin Nine-Difficulties Nun. She is one of protagonist Wei Xiaobao's seven wives. The
阿- prefix is a southern affectionate address marker (compare
阿婆,
阿明), and
珂 is a kind of jade-like white stone — the name evokes elegant beauty.
