Xing Han Can Lan (2022)

If u like Zhaolusi drama then this is a must watch, it's a historical drama but it's worth it, everything about this drama is great the side characters everybody will leave a impact in ur heart

I suggest watching The Rebel Princess if you enjoyed LLTG.
Both have:
- Cerebral plots
- Good cinematography, set design, OST, costumes, and overall production value
-Serious tension between ML and FL (total power couple)
-Strong, stoic, and feared General (who's a total softy for his woman)
-Small but fiercely intelligent and resourceful FL
-Palace politics (Rebel Princess is more palace politics heavy than LLTG).

Similar elements:
Political intrigue, family, friendship, witty female, female empowerment, growth

In both dramas, the female leads have scheming relatives from which the female leads have to protect themselves.

Two of the best historical dramas, the acting was brilliant and the story is kinda simple in New Life Begins compared to Love like the galaxy but still it has the same impact on me because both dramas were not mainly focused on the ml and fl but showed everyone's story and it was hard for me to complete both of them .

--The clothing and hairstyles are the same.
--Similar social background and rules.
-- Good tension between the FL and ML
-- Just recommend the first half of this drama (EP1-about EP22 ) because they follow the novel
-- Novel adapted drama (author Ma Boyong with other works like ' Luo Yang')

Despite the difference in plots, both dramas are slower paced, slow burn romances, and focus on families with a very large cast of characters. Both FLs are determined and strong-minded, both MLs fall in love at the start and slowly win the FL's heart. The tone and pacing feels similar, too.

Let me tell you with novel pov :
-Both has FL time-travelling to the period where our story starts. Both can't go back to their respective bodies as original soul of the bodies are already died and only soul of FL is survive by time-travelling through our story' main character.
-Both ML served for King of their period and they both have aristocratic family background.
-For FL, both are model student in their respective major, and undoubtedly smart. Their Inquisitive and quirky personality gives headache to their partner yet this is the reason they get attract to our FL isn't it.
-As slow-burned romance should, things are not going well at first in both. But don't worry it's always in Male Chases Females First tag.
-With politic, romance, time-travelling and most importantly period piece with extra comedic spice. I hope you should try this two master pieces for yourself.

Mandatory to watch the first part of this series otherwise you won't understand anything in part 2, so kind of a given recommendation.

-both are historical/costume drama
-both the dramas have good looking cast
- the production of the dramas is outstanding
- both dramas have smart female character

In the sinful city of Heyang, Pan Yue, who was throwing lots of fruit and carts, married Yang Cai Wei, whom everyone despises. On the day of the wedding, Yang Cai Wei was killed, and the suspect was Pan Yue. Yang Cai Wei, who "resurrected from the dead", returned "fiercely" under the guise of "evil girl" Shangguan Zhi and was about to expose Pan Yue's true face.

In the process of bravely fighting against the evil forces of the "Four Great Clans" and investigating old cases, the two hearts came closer again. Yang Cai Wei found out that the real murderer who killed her was someone else, and Pan Yue loved her deeply from beginning to end. Everything is about to be perfect, but the people behind the scenes once again set up a trap, trying to push the two to an end of doom.

Both FLs are resourceful and use their wits to get out of tricky situations. Mainly due to their unfortunate childhood, they have had to learn to be like that and rely on themselves.

Both MLs are generals and have an intriguing dark character.

Another reverse harem chinese drama that has 1 Female lead and 3 Male Leads set in ancient historical China

similarities:
both FL are a general's daughter who is smart and charming.
both FL fall in love with the son/adopted son(in LLTG) of the emperor.
in both the ML seeking the truth about their dead family.
in both the emperor is really smart and have full trust in the ML and later in the FL and also want them to be together.

Completely different storyline but both are the direction towards sadness and loneliness , overcome hardship relying each other
P.s the cinematography is great in both, calm and pleasant.
