Suzaku and Liu Chuyu are twins. Because Shi Tian said that one of the children was a lone star in Dreadwind, the Queen Mother killed her daughter Liu Chuxiu for her position and left a child in Liu Chuyu, but Liu Chuxiu did not die. Suzaku and Liu Chuyu look too much alike because they are twins.

In the TV series "Phoenix Prison", Liu Chuyu returned to the Princess House from the palace, and the guards flew faster and faster, just lost for a while. Liu Chuyu accidentally fell into the lake and was replaced directly, while Suzaku, the killer posing as Liu Chuyu, looked exactly like Liu Chuyu.

Suzaku is a wild child who was saved by the owner of the secret pavilion on the roadside. She was taken to a secret pavilion and trained as a killer. She looks like Princess Liu Chuyu of Yin Shan. With a little embellishment, no one can tell Suzaku from Liu Chuyu. Maoting sent Suzaku to assassinate Liu, and Suzaku and Liu Chuyu changed their identities.

At that time, Liu Chuyu had just come out of the palace and went home with gold, silver, jewelry and noodles given by Liu. As a result, the cow pulling the cart suddenly went crazy and threw Liu Chuyu into the lake. Suzaku hid in the lake in advance, taking advantage of Liu Chuyu's falling into the lake to replace Princess Yin Shan of Liu Chuyu.

Suzaku didn't think there was a reason why she and Liu Chuyu looked alike before. It happened that Liu Chuyu and Liu's mother were ill, so Suzaku had to visit the Empress Dowager. She overheard the Empress Dowager and her handmaid mention what happened that year. It turns out that when the Queen Mother gave birth to Liu Chuyu, she turned out to be twins.
