What are the details of Xiao Jinyu and Xiao Jinli suggesting that they are not brothers?

First, it is clear that Xiao Jinyu doesn't look like Princess or Ma Xu. After the autopsy, Chu Chu said that a person's appearance has a lot to do with his skeleton, and the skeleton is directly related to his parents' appearance. She can roughly restore her mother's appearance according to her mother's remains.

After this, she added, Xiaojinyu doesn't look like a princess and Xu in appearance.

Second, the princess gave birth to twins, but when she was seven or eight months old, she still recorded a child, princess royal, with a noble status, and recorded too many daily medical records of doctors since she was pregnant. The princess claimed that Xiao Jinyu and Xiao Jinli were twins, but they looked nothing alike.

In addition, in princess royal's medical records, until 7 months, there was only one child recorded by Doctor Tai. Although ancient medical skills were not developed, twins may not be diagnosed, but it is also possible that the princess lied and one of the children was not her own.

Third, Xiao Jinyu was in poor health after falling into the water as a child. When Xiao Jinyu was a child, he once fell into the water to save his younger brother Xiao Jinli, and his younger brother also fell into the water. But Xiao Jinyu can't swim by himself, and he is already very weak. This time he got into the water, which made him seriously ill, and his health has been poor ever since.

Therefore, princess royal severely punished koi fish. On the surface, there seems to be nothing wrong with this matter, but is it really because Xiao Jinyu fell into the water when he was a child that he was in poor health?

With the development of the plot, we know that drowning was skillfully used by princess royal. Xiaojinyu's premature birth caused her congenital weakness. It just happens that this matter can be used as an umbrella.

In addition, Xiao Jinyu will feel dizzy and uncomfortable when he meets a place without windows, which is a symptom of claustrophobia. However, Xiao Jinyu has lived in the Princess House since childhood. Why does she have such symptoms?

To this end, Chu Chu also specially made a dry Kun mirror for Xiao Jinyu. But the screenwriter didn't explain this clearly, which is also a foreshadowing.
