Because of life, Xuan Ji's name is not Linglong's sister. According to the relevant information, it can be seen that in The Beauty of Coloured Glass, besides the heroine Chu, there is also the identity of her sister Chu Linglong. Linglong has always been very good to Xuan Ji, taking care of her sister everywhere in her life and not letting others bully her. Due to the decline of family fortune, the two lived under the fence, not calling each other sisters and protecting each other.
