In the novel, when Longyue was just born, Zhen Huan asked the emperor for permission to give her a name (Longyue is a title). Zhen Huan named her "Wanwan", which is homophonic to "Wanwan". The article wrote: "I don't know if he thought of Queen Chunyuan when he called her like this, but he did indeed love his daughter very much. With this similar name, my daughter can be like her father. Love, she is not a man, so she will not be involved in the battle for the crown prince. This love is enough to prevent her from being despised, but my daughter's future depends on the Queen Chunyuan who looks similar to me. On my body, I only feel sad, and the sadness is even more desolate."
So the necklace she gave to Haoyue also has this meaning, which is to protect Haoyue. Her biological mother is not around, and she only has the love of her father. Only then can she not be bullied or looked down upon in the harem. Since the emperor can never forget Queen Chunyuan, then Wuyue has a similar name and similar things to Chunyuan, and Wuyue's status in the emperor's heart is different from that of other princesses. A princess is different from a prince. The princess' future depends entirely on her father's favor. She wants to fight for a good future for her daughter, even if she is not around. Hope to adopt~
