In The Legend of Qin and Nine Songs of the Heavenly Path, Wei Zhuang's sister might be a fictional character setting because these two works were fictional stories without real reference information. However, if Wei Zhuang's sister existed, her personality and appearance might be different from Wei Zhuang's because everyone's personality and appearance were unique. According to the setting of The Legend of Qin, Wei Zhuang was a very powerful swordsman and warrior. His personality might be calm, decisive, confident, and mysterious. If he had a younger sister, she might inherit his martial arts talent and have a personality similar to his. She might be an equally powerful swordsman or warrior.
