Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
van nang » van quang, van ban, van dong
te sach » toc sach
cam luc » cam xuc, cau luc
va hanh » van hanh, va thanh, va danh
hanh va » hang va, hanh vi
cua tre » cua te, cuu tre, dua tren
v nang » va nang, vu nang, voi nang
va cam » va cham, va cac, va cao
luc va » duc va, tuc va, loc va

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