JustI just finished reading my friend’s post about a single Japanese father who has lived in Paris for 15 years but stills struggles daily with the locals.

This sentence, along with the following 2 should all be combined into the same sentence.

About a Japanese single father livingsingle Japanese father who has lived in Paris for 15 years.

But still struggles with daily life problems with the locals.

I lived in the UK for 7 years as a students.

Even that is consider wased a long a period of time.

But as a student I don’idn't have to dealing with as many problems.

Like paying tax, working stress…

Having said that, just like my friend’s experience in the UK there are many rules and systems that I found were difficult to understand.

This sentence as well as the following sentence should be combined.

In UKthe UK there are many rules, and system…s that I found that difficult to understand.

LI later I realized that it was because I always used to compare it with my mother country to compare.

In fact, I should put that aside first.

I think that this is grammatically correct but it makes no sense in this context. I think what you meant to say was, "I should put aside my bias", or something along those lines.

Therefore that makes meI would feel better.
