CNiQIYI

A psychology PhD from the modern world wakes up in the body of a disgraced concubine, banished to the palace's Cold Palace after being framed for poisoning the emperor's heir, with her entire family executed for it. With nothing left to lose, she starts using everything she actually knows — reading people, forensics, medicine — to win over the handful of people around her and slowly claw her way back from the bottom of the palace hierarchy, determined to expose who really framed her family.
