Chu Ying stayed at Lei's house for two days and got along well with Yan Family. The night before they returned to the palace, the Yan family specifically went to Chu Ying and told her that they hoped to let a child take Lei Mingji's surname in the future, but Chu Ying refused this proposal.
Chu Ying's reason was also very simple: "When a child was young, if he had a different surname from his brothers and sisters, he would feel excluded, which would be harmful to his physical and mental health."
Even in modern times, two children with different surnames will be questioned at school. Moreover, in terms of his eldest brother's temperament, a child surnamed Lei may be treated differently. In such an environment, children may be related to their brothers and sisters
