I went Thailand.

I went to Thailand.

I went to Thailand last week.
Thailand is very hot and clean up everyday. (It's hard to understand what you mean. Did they clean your room everyday?) 

In my hometown, there is a lot of snow lies and it is very cold in winter. 
So Thailand is enviable to me. (You can say 'I envy Thais' instead)

This travel was very nice. (Though it's not so wrong, stylistically it's not correct)

Now, I can hardly speak any foreign language,
but I would like to communicate with many people in the world .

I'll try to carry out learning English 2013!
