Perhaps you should try some spelling variations:
thanh ha » thanh hoa, thanh hai, nhanh ha
dang xa » dang xay, lang xa, dang ha
hieu ve » hieu va, hieu van
ha cua » hoa cua, hai cua, nha cua
loc va » hoc va
ve cac » va cac, vien cac
luc va » duc va, tuc va
sac ky » cac ky
cua te » cua tu

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: va ((sac ky) OR (sai ky)) dang xa hoi. hieu ve cac ((luc va) OR (loc va)) thanh ha cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "va ((sac ky) OR (sai ky)) dang xa hoi. hieu ve cac ((luc va) or (loc va)) thanh ha cua te~".
• Adding a wildcard symbol may retrieve word variants: va ((sac ky) OR (sai ky)) dang xa hoi. hieu ve cac ((luc va) or (loc va)) thanh ha cua te*.
