Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
su triet » su viet, su tien, ve triet
cham xuc » cam xuc, chat xuc, cham soc
va hanh » van hanh, va thanh, va danh
su sach » so sach, vu sach
hieu ve » hieu va, hieu van
nang xa » nang x, lang xa, nang ma
te sach » toc sach
ve cham » va cham, ve chat, vu cham
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: ((su sach) or (te sach)) ky nang xa hoi. hieu ve cham xuc va hanh vi ((cua triet) OR (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (te sach)) ky nang xa hoi. hieu ve cham xuc va hanh vi ((cua triet) OR (su triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (te sach)) ky nang xa hoi. hieu ve cham xuc va hanh vi ((cua triet) OR (su triet))".
• Adding a wildcard symbol may retrieve word variants: ((su sach) or (te sach)) ky nang xa hoi. hieu ve cham xuc va hanh vi ((cua triet) OR (su triet))*.
