Great Job, Rose! Below is the edited version for your review :)

Gyeongsangbukdo consists of 23 municipalities and cities.
They are is mostly farming villages and contryside areas.
When I was a child, I lived in Taegu and hardly visited the countryside, so I didn’t know what life there was like.
My first workplace was in Sangju, and I moved to the countryside.
At first, I wasn't accustumed to living in Sangju.
People there are unkind, because at that time outsiders(people out of city) seldom came and went there, and people living there know one another.
Outsiders like me are not their concern.
As time goes by, the atmosphere of the society has gradually changed.
They realized that if outsiders or tourists don’t visit there, it will not develop and remain unknown.
