Perhaps you should try some spelling variations:
hieu vien » hieu hien, hieu viec, thieu nien
hanh doi » thanh doi, hanh noi, hang doi
van hanh » van thanh, ban hanh, van anh
doi cua » dai cua, hoi cua
cac xuc » cac nuoc, chat xuc, cac cuoc
te sach » toc sach
ly vang » ly hang, ly van, ly quang
ly nang » ky nang, ly hang, ly quang
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) OR (ly vang)) xa hoi. hieu vien ((cac xuc) OR (cam xuc)) van hanh doi cua cu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ly nang) OR (ly vang)) xa hoi. hieu vien ((cac xuc) or (cam xuc)) van hanh doi cua cu~".
• Adding a wildcard symbol may retrieve word variants: te sach ((ly nang) OR (ly vang)) xa hoi. hieu vien ((cac xuc) or (cam xuc)) van hanh doi cua cu*.
