Perhaps you should try some spelling variations:
cua triet » su triet, va triet
cua viet » ca viet, hoa viet, cua vat
hanh lai » hanh lam, hanh tai, thanh lap
hieu van » hieu va, thien van, lieu va
va hanh » van hanh, va thanh, va danh
tu sach » thu sach, su sach, tu cach
bao xuc » bao luc, bao thuc
nang xa » nang x, lang xa, nang ma
te sach » toc sach
van bao » van ban, van dao
xuc va » duc va, tuc va, luc va

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) or (te sach)) ky nang xa hoi. hieu van bao xuc va hanh lai ((cua triet) OR (cua viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) ky nang xa hoi. hieu van bao xuc va hanh lai ((cua triet) OR (cua viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (te sach)) ky nang xa hoi. hieu van bao xuc va hanh lai ((cua triet) OR (cua viet))".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (te sach)) ky nang xa hoi. hieu van bao xuc va hanh lai ((cua triet) OR (cua viet))*.
