"I prefer tea rather than coffee" is correct. or you can say "I prefer tea." "I'm leaving Cambodia for Japan" is awkward; but OK. You could say "I'm moving to Japan. I'm going to Japan. I am traveling from Cambodia to Japan.

I prefer tea to coffee I prefer tea rathe than coffee Both correct ways of saying it ! Leaving Cambodia for Japan ! ( not to)

Thank you very much :D

The first one is missing a comma. I would write it as, " I prefer tea, rather than coffee." It could also be "I prefer tea over coffee." The second one should be, "I'm leaving Cambodia for Japan." Or maybe "I'm leaving from Cambodia to Japan." Hope this helped
