Perhaps you should try some spelling variations:
hieu viec » nhieu viec, hieu ve, sieu viet
van danh » van doanh, van anh, van hanh
danh lai » danh sai, gianh lai, dinh lam
tu sach » thu sach, su sach, te sach
nang xa » nang x, lang xa, nang ma
cua tre » cuu tre, cua triet, dua tren
sach ky » sac ky, sach y, sach ty
cua te » cua tu
cac co » cac cong
cac lo » cac lop, cac bo, cac ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky nang xa hoi. hieu viec ((cac lo) or (cac co)) van danh lai ((cua tre) OR (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky nang xa hoi. hieu viec ((cac lo) OR (cac co)) van danh lai ((cua tre) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky nang xa hoi. hieu viec ((cac lo) or (cac co)) van danh lai ((cua tre) OR (cua te))*".
