Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
nhan luc » nang luc
van hanh » van thanh, ban hanh, van anh
te sach » toc sach
sach ky » sac ky, sach y, sach ty
nang xa » nang x, lang xa, nang ma
hau loc » huu loc, phau hoc
hanh de » hanh ve, hanh kem
cua tre » cua te, cuu tre, dua tren

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky nang xa hoi. lieu va ((hau loc) or (nhan luc)) van hanh de ((cua tre) OR (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang xa hoi. lieu va ((hau loc) OR (nhan luc)) van hanh de ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang xa hoi. lieu va ((hau loc) or (nhan luc)) van hanh de ((cua tre) OR (cua triet))".
• Adding a wildcard symbol may retrieve word variants: te sach ky nang xa hoi. lieu va ((hau loc) or (nhan luc)) van hanh de ((cua tre) OR (cua triet))*.
