Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hanh dao » lanh dao, thanh dat, thanh dam
hanh tai » thanh tai, hang tai, han tai
hieu van » hieu va, thien van, lieu va
sach ky » sac ky, sach ty, sach kem
van cau » van dau, van hau, van chat
lang xa » lang ha, dang xay, lang van
cau xuc » cam xuc, cau luc, cau truc
xuc va » duc va, tuc va, luc va

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 ky) OR (sach y)) lang xa hoi. hieu van cau xuc va ((hanh tai) OR (hanh dao)) cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) OR (sach y)) lang xa hoi. hieu van cau xuc va ((hanh tai) or (hanh dao)) cua triet~".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) OR (sach y)) lang xa hoi. hieu van cau xuc va ((hanh tai) or (hanh dao)) cua triet*.
