Wei Zi is the queen.

The swallow was very angry. She couldn't find Wei Zi, so she went to the emperor early the next morning to help her important people. At first, the Queen denied it, but later, there was no way to argue that she wanted Wei Zi. The emperor flew into a rage when he saw such a treacherous mother who abused her private affairs so viciously. He just said, if you can't be the mother of a country, it's better to abdicate and make way for her.

The emperor can abolish the queen for crape myrtle. No wonder the queen hates crape myrtle and swallow so much.
