Dreaming Back to the Qing Dynasty (2019)

Both similar in terms of time travel.

In DBTTQD, the female lead goes into the past to find the prince she fell in love with in modern times (due to an ancient object they were able to meet but they were later separated).
In LBTI, the female lead enters a game (That is historical themed) and falls in love with someone unexpected. (This is a Wuxia drama)

DBTTQD is more of a Political drama whereas LBTI is Wuxia. But both stories contain Fantasy and romance. :)

Both FLs are modern day women who time travel to the past and enter the palace, encountering the many princes there.

They have a similar story relating to the princes and time travel. Moon Lovers is a bit darker drama.

Both have a time travel to Qing dynasty. In Palace it's happens by an accident, in Dreaming... (according to the synopsis) the girl has her own abilities.
In both she get's a love interest in one of the Qing princes.

Very similar dramas
TEL is about a girl who goes back into the past and she finds herself sharing a body with another woman (Fl is more outgoing whereas the other is serious and silent) who tried to commit suicide due to being forced into a marriage with the 8th prince, stopping her from being with her lover. Our female lead falls for the 8th prince, causing the 8th prince to be confused by the true personality of his lover, what is her true personality?

In DBTTQD, the female lead goes into the past to find the prince she fell in love with in modern times (due to an ancient object they were able to meet but they were later separated). The leads go through struggles when the fl goes into that past as they both forget each other upon the fl's arrival, the fl needs to try and fit in as she tries to remember the reason for her travel into the past and remember her true lover.

Both dramas show the male leads fighting for the throne and power whilst trying to protect the female lead.

Similarities :-
~ both drama are historical and romance
~ the main lead once fall in love with each other, then they forget their lovers, and fall in love again with each other.

They are both similar in terms of time travel but they don't really have a similar plot.
In DBTTQD, the leads met in modern times due to a magical object (She had a lantern and it allowed the prince from the past to come into her home when he slept, they fell in love during this time) , but they were then separated, causing the female lead to go into the past and find him.

UL is about a girl who enters a game to find her true love, the area she goes into is historical and she meets a lot of nice men but the one she falls on love this is the man she hates.

UL is more of a comedy whereas DBTTQD is more political. But both dramas contain, Fantasy, Action, Wuxia and Romance(More Romance in UL) :)

Both female leads time travel to the past. Difference male lead from Dreaming back to the Qing Dynasty gets to meet the female lead in her time, and the male lead in the Cinderella doesn't meet her until she gets to the past.

The concept is somewhat similar where both leads time travel to each others' world with an unknown reason. Hence, they try to figure out what is going on and how to travel back to their own worlds. Along the way, they end up falling in love with each other.

Time Travel
Destined Love
Romantic Moments
Conflicts in the Palace
Martial Arts meets CGI
Interfering with History
Modern World vs. Ancient Dynasty

I'm a history buff, and although Dreaming Back is a fictional time travelling romance drama, the history of the Kangxi era is seemingly accurate. If you like to watch more about the Qing Dynasty, The Story of Yanxi Palace is a must-see drama about the Palace politics and the strive for power.

Both of the female leads travel back in time to the Qing Dynasty. There, the female leads capture the attention of the princes and get entangled with them.

Both have:
-Time travel
-romance
-court power battles
-secrets
-lighthearted plot yet with painful moments

If you like both kdramas and cdramas and you like historical romance with time travel, then you might like both of these dramas.

Both dramas are set at the time of the Nine Lords' War.
Both dramas show the princes' endless scheming against each other to secure their position/reputation as a worthy crown prince/emperor to their father.
The female leads in both dramas eventually gets involved with politics and the princes - though with which prince differed between the two.
Both showcased aspects of arranged marriages, as well as marriage alliance.
