I have Chinese friends in England that say the same thing! Living in London, there is absolutely no pressure to get married at all, let alone before a certain age. I think it's only natural that parents project their mentalities on to their kids, it's inevitable. But then changes are created by those kids that decide they want to do things differently.

Here are some corrections!

A girl's 25-28th

It's my first note ,^ ^
I'll write something about the [age as a noun takes a zero particle, which means you don't use the/a unless you're talking about a historical period of time e.g. 'the Ice age'] age. I‘m 25 years old,how [we use 'how' when asking questions to do with describing states e.g. 'how do you feel' or actions e.g. 'how do we bake the cake?' In this case you refer to opinions, thoughts, so we use what] do you think of a girl's 25-28th .Does it looks quite old to a girl's life [use of does suggests you are asking a question, so we need a '?' at the end]. In China,parents may urged [you've used the past simple '-ed' instead of the present simple 'urge'. You are describing a habitual action that is still occurring, so it's present ] their children to find a gf or bf as soon as possible,and rapidly to get married!OMG!
When i was a student in school last year ,i often heard about how impatient of [not sure why this is here- maybe you were thinking in Chinese and tried to make 'impatient' possessive, like 'the impatience of the parents'. It can be expressed simply as 'impatient parents'] parents to treat their kids' marital status.But when i graduated and are working,i can't bear it,but if i show the angry to my parents,they may feel sad.
Isn't 25-28 or older are the happy ages in your life?Shouldn't we spend more time and energy to work hard,enjoy the single life?to travel to more intresting places,see more beautiful scenery,doing more intresting things we want to and never did,learning more skills and knowledge.
And what's wrong with this world ?Would it be ok?i was soooooo confused.
How about your country? how do you think of a girls 25th-28th.
