Perhaps you should try some spelling variations:
hieu viec » nhieu viec, hieu ve, hieu hien
sieu viet » su viet, dien viet, bien viet
tu sach » thu sach, su sach, te sach
vai cuu » vai cua
anh vai » anh va, anh bai, anh van
van anh » van thanh, tuan anh, van minh
cuu tre » cua tre, cau tren, cau treo
sach ky » sac ky, sach y, sach ty
nang xa » nang x, lang xa, nang ma
cac bo » bac bo, cac co
cac lo » cac lop, cac co, cac ho

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: tu sach ky nang xa hoi. ((hieu viec) OR (sieu viet)) ((cac lo) OR (cac bo)) van anh vai cuu tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky nang xa hoi. ((hieu viec) OR (sieu viet)) ((cac lo) or (cac bo)) van anh vai cuu tre~".
• Adding a wildcard symbol may retrieve word variants: tu sach ky nang xa hoi. ((hieu viec) OR (sieu viet)) ((cac lo) or (cac bo)) van anh vai cuu tre*.
