My home town

My hometown is Guang'an ,it is situated in mostly hilly areas. The main crops here are rice,wheat and rapeseed . In summer,when the rice matures, my family and I become(because probably you mean that the action is regular from year to year) busy harvesting rice.
cos there are mostly hilly areas where I live, so we cannot use the outdated technology harvesting rice, we must use behind the harvesting , but we are very happy .
Now i went to Beijing for two years,with little time back home,so hard to feel the joy of harvesting(gerund). sometimes i feel always alone without my family, i've lost my love at last week, i try to find a better job to paralysis myself.

I think everything will be alright!

I am correcting your essay to show you the fluidity of the English language so that you can compare and learn.  Videoflores had done an excellent job in correcting your grammar spelling etc.  However he did not edit your sentiments correctly.  Hence it makes no sense in your rice harvest.

Now that I am living in Beijing for two years now, I did not have much time to return home to feel the joys of harvesting the rice plants manually.  I always feel alone without my family.  Last week, I lost a loved one.  I need to find a more interesting job to numb my pains and sorrows. My regrets of not able to spend more time with my family.2

1.  Just like in Chinese, we have 米 and 飯 to distinguish the two.

2.  I felt that your conclusion is rather weak and incomplete.  Hence I added the last sentence to better express your sentiments.
