Listen,to the sound of that year

While I was having a cup of tea ,and listening to someone's song that I forgot by who ,my mind was absent, for I was remembering something in the past. I was drinking tea ,listening to the same song ,in the residential college.I had long hair that year.I used to walk along the LIjiang River alone.The water was very clear.The moon shone brightly. Someone was  barbecuing by the riverside.

I breathed freely. It has been almost 9 years. 

I can't go back.

*Note: there should be a space after a fullstop, not before. Remember your articles. Also, keep the same tense in the sentence and preferably throughout the paragraph. Also remember prepositions. There were some plural errors too. 

Someone's barbecued riverside - this implies that the riverside is owned by someone and they barbecued it.

I am not sure if you breathed freely after remembering the incident or if you breathed freely in the memory (perhaps breathing in the scent of the riverside barbecue?)

All in all, it is quite a nice piece of writing, very poignant.
