Actually, the file I emailed you yesterday has included housing allowance & home trip allowance summary. The category " house renting allowance" is the same as housing allowance. Some expats has the benefits of 2 or 4 times home trip from working location to hometown while some other local staffs (high level )has the similar benefit of transportation allowance, but there's no standard or guide for these benefits, it's always case by case. There are many factors can impact candidate's package, so I think most date of left employees which I have provided to you has less value, maybe the updated maket date can give you more reference.
