Perhaps you should try some spelling variations:
hieu vien » hieu hien, hieu viec, thieu nien
van hanh » van thanh, ban hanh, van anh
te sach » toc sach
doi cua » dai cua
ly nang » ky nang, ly hang, ly vang
nang xa » nang x, lang xa, nang ma
cac xuc » cac nuoc, chat xuc, cac cuoc
sach ly » sach y, sach lo, sach ty
hoi cua » hoi chuc

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