1. In my opinion, the name of the second-born boy should match the name of the first-born girl, and at first glance it looks like a brother and sister. Therefore, the name should also take three words, and the second word should be consistent, but because the word "Jing" of the first-born daughter is generally used for girls' names. Therefore, the word "Jing" can be used for boys' names, which are generally used for boys' names.
2. To sum up, the second-born boy can be named as Hu Jingwei, Hu Jingyan, Hu Jingting, Hu Jingfeng, Hu Jingfeng, Hu Jingan and Hu Jinglin.
