I think you don´t understand the concept of idiom, wich is logical in different cultures.
And Idiom is not a "Saying", in your example there is a saying: "A womand is sweet etc".Redrose wrote:maybe as a Chinese saying gose:"a woman is sweet, two women are sqrrows, three women are soldiers
In english there are sayings too but they aren´t idioms. And Idiom is a figurative and coloquial sentences that people use to say the same thing that in formal english.
Example of IDIOM
formal english Idiom
EASY A PIECE OF CACKE
Example of saying to procastination or for laziness
"A conclusion is simply the place where yopu got tired of thinking"
And Idioms Red Rose are very important because as a foreing students we can lear lots of grammar, but in the real life if you go to a some country where people speack english it is sure you won´t nderstand anything because they use idioms in all the cases.
Remember that:
"Everyone has photographic memory. Some just don´t have film"
I´m sure you have too much films. I don´t have one
