I don't know if you are writing poetry or just prose.  If it is poetry, it is excellent except that you have to indent the following way.

A poor rural area

Is where I grew up.

For twenty-four years,

At the least.

My parents,

Farmed everyday and night.

Little Brother Feng and I,

Always at farming after school.

However, if you are writing prose, then I'm afraid that it is not how one should be writing.  Here's the prose form:

I grew up in a poor rural area for at least twenty-four years.  I have a small family, my father, my mother and my little brother, Feng.  My parents are farmers and they worked every day and night.  My little brother and I always help out on the farm after school.
