I recommend a novel. The female protagonist's name is Little Tree. She was born with memories of her previous life and was gifted. She was mistakenly replaced by someone else's child by her nanny. Her female teacher was very outstanding.

In a novel, the female protagonist seemed to be called Little Tree. She knew everything when she was born and had memories of her past life. She was replaced by her own child by Nanny. The female protagonist had a very powerful female teacher who also had memories of her past life when she was born. The male protagonist was a prince and did not let the palace maids around him bathe for the sake of the female protagonist. The female protagonist was originally surnamed Liu. The Liu family had generations of queens, but they could not have children. The female protagonist's family inherited a sweet taste. The female protagonist gave birth to a child with the male protagonist because of the medicine given by Nanny before they finally married. I'm begging for the name of the novel. It's a novel that I've read and published in 10 years.
