There are two Liang Weiwei with the same name and surname, with the same appearance. One is a modern social worker who is involved in social affairs, and is overwhelmed by life; the other is the legitimate daughter of an ancient prince, trapped in a deep house and unable to control herself. Pulled by an ancient jade, time and space suddenly shifted. Modern Liang Weiwei traveled to ancient times and became a noble lady with rich clothes and fine food but strict rules; ancient Liang Weiwei accidentally fell into modern times and fell into the fast-paced, unruly but free and lively urban world. Exchanging worlds and identities, they stepped into each other's lives and learned to adapt to the unfamiliar fireworks and ups and downs. At the two ends of the millennium, they each restarted and grew up. Let's see how the two Liang Weiwei live a brand new version of themselves in each other's world.
