Both the Deer and the cauldron and Demi Gods and Semi Devils are jinyong's novel, tbh some of the martial art in Deer and the cauldron is from Demi Gods and semi Devils but much much weaker, even jinyong himself said it. Most of the casts are similar especial the actress are almost the same and male lead Han Dong. The director for both of this Tv series is Samson Lai Shui-Ching and he also acted as "Ao Bai" in The Deer and The Cauldron and "Wang jiantong" in Demi Gods and Semi Devils

it's a realistic story of a couple who juggles between their love life also their career, trying to survive life as a beijing drifter

In both, the profiler plays an effective role in discovering the truth through the analysis of criminal psychology and examining the role of the environment in criminal behaviour.
In both, the viewer closely observes the criminal's daily life and behaviours.

Both dramas are about crime and criminal investigations. In both viewers can observe the behaviour of criminals.

princess of Jia Nan grows up in the palace since childhood. She remains carefree despite knowing that there is no freedom within the palace walls and does not want to be used as a puppet.

Thus, relying on her own ingenuity, she resists the fate of becoming a tool in the inner palace fighting.

Li Qian, a guard of the Imperial Army, wants to understand the truth behind some events many years ago. He works hard to seek a higher position in the palace, just to get relevant clues.

They are two people with vastly different personalities who meet by chance and love each other. In order to reverse their own destiny, they work together, look forward to breaking through the barriers of identity and stay with their loved ones for a lifetime.

ML is both movies return to hometown.
They both get stranded in the island due to unavoidable circumstances.

Similar character setup story genre. The drama also focus more on the female lead's power over the male lead.

Both gave me the similar vibes....in both main leads are in college. One of them is bit shy in revealing their relationship in the beginning because of parents' while other main lead's family is open minded. One of their acquaintances causes misunderstanding between the main leads. In both the series, there is one common friend who knows about their relationship (in DBK its female friend but in TT its a male friend). At the end, its one main leads who clears the misunderstanding by his tactics. In both, the main leads have awesome chemistry. Both are worth watching

a police team solving cases together
not a super thriller element to either of them
focus more on the science of the case than on entertainment
good to watch while eating dinner -- not too fussy or stressful

Leap Day is supposed to be both a sequel and prequel to 940920. A story with same cast that happens in a different space-time. The female lead from leap day ends up in the time-space dimension of 940920. Episode 10 of Leap day could be considered as the first episode of 940920. In order to avoid confusion, watch Leap day before 940920. And for those who are confused by the ending of Leap day, the answer is 940920.

Drama about three women instead of two in their thirties dealing with love and life. The two college friends are married. One couple is struggling with an apathetic husband and the other is the model for a perfect marriage. The third friend is someone they befriend later was never married who is focused on her career.

Not a gender-bender or time-travel. But in similar manner there are fake identity crown princesses, Mr. Queen is a man from the future inhabiting the crown princesses body, in Fake Princess the crown princess is a look-a-like that gets swapped in for the real crown princess.

In both stories the ML (crown prince) is suspicious of the FL (crown princess) as she comes from the "enemy camp". Also in both stories the ML (crown prince) is also under threat from enemies all around him and must behave low-key and plot secretly with few allies.

The stories are quite similar, romantic and funny with a more serious undertone, fight scenes, plotting, and mostly the pull and push relationship between the ML and FL where they battle suspicion and romance between each other.

In both movies :
- Friends travel to what happens to be a hunted place and try to survive.
- Absolutely funny cowardly characters.
- Hilarious iconic lines that you'll remember for the rest of your life.

PeeMak is more sentimental and just legendary.
