How to say "Princess Zhu Huan II" episode 28 Wei Zi is not the emperor's daughter?

Because Wei Zi, the swallow, let her go with fragrance, the emperor suspected that it was Wei Zi, so he asked Wei Zi's uncle and aunt and the midwife who delivered Wei Zi's baby that year. They were bribed by the queen to talk nonsense about Wei Zi's birthday in front of the emperor, so the emperor thought that Xia had designed a scam and was very angry, so they were not the daughter of the emperor.
