Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
toc sach » hoc sach, doc sach, thuoc sach
cham xuc » cam xuc, chat xuc, cham soc
su triet » su viet, su tien, ve triet
hieu va » lieu va, hieu qua
va cham » va chat, va tham
dinh vi » dinh ve, dinh viet, dinh tri
y nang » ky nang, ly nang, v nang
xuc va » duc va, tuc va, luc va
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: toc sach y nang x hoi. hieu va cham xuc va ((hanh vi) or (dinh vi)) ((cua triet) OR (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach y nang x hoi. hieu va cham xuc va ((hanh vi) OR (dinh vi)) ((cua triet) OR (su triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach y nang x hoi. hieu va cham xuc va ((hanh vi) or (dinh vi)) ((cua triet) OR (su triet))".
• Adding a wildcard symbol may retrieve word variants: toc sach y nang x hoi. hieu va cham xuc va ((hanh vi) or (dinh vi)) ((cua triet) OR (su triet))*.
