The Qiao family's situation was rather complicated.
Qiao's father, Qiao Zhengyuan, was 73 years old. His first wife had died when he was 45 years old. Two years later, he married his secretary, Liu Yiqin, who was Qiao Yanjue's mother.
Qiao Zhengyuan and Liu Yiqin had an 18-year age difference. When Liu Yiqin married the elder Qiao, she was 29 years old, while Qiao Zhengyuan's eldest son, Qiao Weiyue, was already 19 years old. His younger siblings, Qiao Weisen and Qiao Zhiqing, the boy-girl twins, were 16 years old.
Qiao Zhengyuan met Liu Yiqin one year after his wife's death and got married only one year after that.
However, in the opinion of the three siblings, Liu Yiqin was still the homewrecker who had destroyed their family. Perhaps their mother's death was also related to Liu Yiqin.
A few years ago, they were still looking for evidence of Liu Yiqin's plots against their mother—of course, they didn't find anything.
