When I was a primiary school student, the tuition was over 300 yuan each semester.

My father iwas a teacher, and his salary was similar witharound the same as my tuition.

At the beginning of the semester, the teacher in charge would ask me in public for my tuition in public.

I was very embarrassed but I couldn't say anything.

I disliked the teacher forbecause of her behaviour, because sr. She could have asked me privately.

Furthermore, she knew my father and she knew that he wouldn't be bilking pay the tuition.

I have never heard the word "bilking" before and I had to look up what it meant. It is not a common English word at all. You used it correctly, but it doesn't sound like natural English, at least not in the United States.

I studied in town, and I seldom heard that somebody dropped out because of povertythey couldn't afford the tuition.

"because of poverty" is technically correct, but it sounds strange to me. "couldn't afford the tuition" is how a native speaker would say it.

When I went to middle school, which iwas the only one in town, I experienced my classmate dropped out because of povertythey couldn't afford the tuition.

I was the monitor, and my father happened to be the teacher.

Not sure what "monitor" means here. Hall monitor?

In the second semester, there were five students in my class had dropped out.

My father told me to call them byon the phone, but when we sat in the office, he gave up and said it wouldn't work because he had experienced this so many times.

I wanted to try, but I thought that maybe my father was right, and even though. Even if I called, what canould I do?

There were some students droppeding out every semester, o. One of the main reasons was that they didn't like studying.

There were so many factories in the province, and it wasn't very strict to work in the factories.

I'm not sure what you mean by "wasn't very strict to work in the factories". Maybe you mean "it was easy to get a job at the factories."

So most of them would go to work after quitting school.

It's important to clarify what it was that they quit.

If you wanted to go to college, you had to graduate from high school.

And the tuition of high school was over 1,000 yuan, while the mobilecell phones had just started to bebeing used in the small city.

You need a comma for 1,000. Also, "mobile phone" is correct, but today "cell phone" is much more common, at least in the United States.

I can still can clearly remember that I got two admission letters of my girl classmates after the senior high school entrance examination.

"can still" sounds more natural to me than "still can", but either one is correct. Also "I got two admission letters of my girl classmates" sounds awkward and I'm not entirely sure what you mean.

4 high school, whose students were able to accepted by the colleges rather than university.

Her father answered the phone and told me that she had went to work at a factory.

In most traditional families, sons weare the most important, because the parents think that they can rely on their sons twhen they becomeget old.

InAt the same time, daughters were tregarded asated like water because they would get married and moved out in the end.

I know what you are saying here, but it's hard for me to come up with a more natural way to say it.

There is a saying that goes: when you splashe the water out, you can't never get them back.

"can't never" is a double negative and you should avoid them.

Ironically, some boys were spoiled toso much that they became sovery rude and behaved badly, and t Their parents couldn't rely on them butand even had to support them in turn.
