Perhaps you should try some spelling variations:
hieu vien » hieu hien, thieu nien, hieu tieng
hieu viec » nhieu viec, hieu ve, sieu viet
hanh doi » thanh doi, hanh noi, hang doi
van hanh » van thanh, ban hanh, van anh
doi cua » dai cua, hoi cua
xuc van » duc van, luc van, vuc van
te sach » toc sach
sach ly » sach y, sach lo, sach ty
nang ma » tang ma, sang ma, nang cao
nang xa » nang x, lang xa, mang xa
cua cu » cua chu, cua cau, cua su

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: te sach ly ((nang xa) OR (nang ma)) hoi. ((hieu vien) OR (hieu viec)) cam xuc van hanh doi cua cu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ly ((nang xa) OR (nang ma)) hoi. ((hieu vien) or (hieu viec)) cam xuc van hanh doi cua cu~".
• Adding a wildcard symbol may retrieve word variants: te sach ly ((nang xa) OR (nang ma)) hoi. ((hieu vien) or (hieu viec)) cam xuc van hanh doi cua cu*.
