按照中文可以译成这几种（比较不好）：
You're tired.
You’ve had a hard time
You’ve gone through a lot of hardships
建议可以分别用不同的方式来表达这个意思：
（1）对远道而来的人可以说：
Did you have a good trip?
You must have had a tiring journey
You must be tired from such a long trip
（2）对刚刚完成一项工作的人：
Well done.That Was a hard job．
Good work /Good job ,You’ve got a hard job．
或者直接说Good work /Good job
