英文”又”的問題

"又唔係屋傾!?" = He is not home again?
You could also consider these:
How come he is not home again?
He never stays home.
He went out again?

Very similar to the first one:
"又上左大陸!?" = He goes to China again?
He goes to China all the time.

Hope this help.

They is a few meanings:

1.again
2.further
3.also
4.but
5.and
