Both are adapted from the same manga.

-In both dramas the couple marry very early because a arranged marriage but slowly they fall in love and become a power couple.
-Both ML are highly intelligent and look down the FL at first because of their simple ways and lack of formal education but they start to love and admire them and learn that the life knowledgement their wives have is actually as valuable as the knowledgement from the books, both are complementary.
-Both dramas have very funny and adorable side characthers.
-Both criticize the women inferior place in society and sisterhood is very strong
-Slice of life

The biggest diference that can let down New Life Begins fans is that the FL in The Lady in Butcher's House isn't a cutie, she has a very strong personality and often uses brute force against the ML who is actually weak unlike the NLB ML who just pretends being weak

- Both with Luo Jin playing almost the same character. Lol
- Slice of life, meaningful stories and characters with great development

Similarities:
- Female centered, strong female leads
- One of the FL also was sold to a brothel because a crime of her father
- Women fighting together to survive and succeed in the patriarchal society
- Amazing cinematography, direction, acting, beautiful and meaningful dialoges.
- Weak men causing trouble to amazing women, even the actor is the same (ok, in Marvelous Women he is not so bad as Ouyang Xu lol)

The similarities:
- ML loves FL since school but they were always fighting and she never thought romantically about him before.
- ML admires her intelligence and after becoming her boss he is always challenging her, trying to get the best of her but she thinks he just hates her.
- In both dramas the FL don't achieve their dream because of family problems.
