Why does the new pearl return also mean that the swallow changed the name of Xiao Jian and Ziwei never called May or Brother?

The brother-sister relationship between Ziwei and Yongqi is obviously compared with that between Swallow and Xiao Jian. Since the Swallow and Xiao Jian became acquainted, they have always been elder brothers and younger brothers. For Ziwei, she was raised by Xia Yuhe alone, and she didn't have the love of Emperor Amar since she was a child. Such a growing environment will inevitably be mixed with gossip, which will also have a certain impact on Ziwei's character. In addition, the weak royal family ties make it difficult for Ziwei to be like Xiao Yan.
