It's lonely these days without friends. I think I’m lazy because the cold weather. It’s about 0c here and I didn’t go haven't gone to Menten these days.
Viktor said Sweden always raining in Dec,the cold and wet air makes him upset. Christmas is coming so he still expecting the snow.
China spring festival is coming. These days I have to work overtime, so that I’ll have more holidays on spring festival. I can’t decide if I’m going to be back to hometown or continue working. I want to save for next trip---Tibet and Xinjiang.
Come on!

I was saw the pictures in the Jacob’s facebook when he stayed in Xinjiang. That must be a very happyiness time. He mentioned something about Suzhou to his friend that made me remember last Christmas when we drank a lot and ate hotpot, but it has been 1 year ago from now.
This Friday, we still have a party in Jinji lake. Last week, Carlos said he wanted to take the party, but then he disappeared, so I can’t connect with him any more. He cautch the caught a cold last week - the weather of Suzhou is too bad. I don’t know if  he is coming back to Colombia for the coming Christmas or because the cold hurt him. I’m nervous for that. I hope he will recover and be back soon.

Yesterday night I searched the BBS of Tianya, I read the article named (美國美嗎？). That’s a great article. I was fall fell in love with it. The author talked to us what he happened in the past 20+ years in America, he used a humor and sad words to tell us all these old things.
The article narrated how Chinese went to USA in that old time(after the second war) of China in that time, many Shanghai people went to America for life,they were work hard, honest, brave and smart. They won the honour, made foreigers fix eyes on them, they’re were great Chinese. Opposite nowadays in China Chinese, we are lie, are ugly, bad so much what’s wrong of us now?????

[You have a good basic understanding of English.  You need work on your tenses (they're horrible aren't they!).  Also, remember to put a space after any comma or period.  Also, I disagree with your last sentence in 3]
