Now,I am a medical college student. I am studying at in Nan Chong, a crowded city of in the Si Chuan Province. I have lived here for half a year, but I have never visited this city before. What a pity! Last Saturday I went to the Western Hills, which are is a scenic spot of/in/within Nan Chong. I was very happy because I went with all of my classmates. We were excited to rush into a bus, excitedly rushed into the bus like birds that just flew away flying from birdcages. Ha-ha... Maybe this was too exaggerated I am exaggerating, but believe it or not, for people like us who had feel the heavy pressure at of our studies, this was these were our real true feelings. That morning we presented flowers to the revolutionary martyrs who devoted their lives to our nation.We should be in honour of them. We heard there was a waterfall, so we left to get there. Although we got lost halfway, we finally arrived at the destination finally.Do you know, we had been gone for four hours. Oh my god! I couldn't believe we had crossed over four hills. And do you know, the waterfall had no water because it was the dry season. All of us were tired, but we had a good time! Next time we will ride bicycles if the weather is nice.

— you don't need to start with "Now", it's clear you're referring to your current situation.

— you said you are studyinig "at" Nan Chong. Since this is a place, not a university, you would say "in". However you would say: "I am studying at ~ University.

— remember to put a space after commas and full stops.

— you liken you and your classmates entering the bus to birds flying from bird cages. Using a comparison like this in English is impressive! However, note that it is a bit confusing to compare the action of entering something to the action of exiting something.

***I made quite a lot of corrections but, believe me, your English is great. A lot of my corrections aren't necessary, but they make your English sound more like that of a native. Good luck with your studies!

The Happy Weekend
