Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thanh ve » thanh va, thanh vien, thanh van
tu sach » thu sach, su sach, te sach
hieu va » lieu va, hieu qua
cac xuc » cac nuoc, chat xuc, cac cuoc
hanh ve » hanh vi, hanh va, hanh kem
y nang » ky nang, ly nang, v nang

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

• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y nang x ho. hieu va ((cac xuc) OR (cam xuc)) va ((thanh ve) OR (hanh ve)) cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang x ho. hieu va ((cac xuc) OR (cam xuc)) va ((thanh ve) or (hanh ve)) cua triet~".
• Adding a wildcard symbol may retrieve word variants: tu sach y nang x ho. hieu va ((cac xuc) OR (cam xuc)) va ((thanh ve) or (hanh ve)) cua triet*.
