Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thien van » thi van
hanh dao » lanh dao, thanh dat, thanh dam
thuc va » thuc vat, thuc dan, thuc day
dao cua » dai cua, day cua, dan cua
te sach » toc sach
van cau » van dau, van hau, van chat
y nang » ky nang, ly nang, v nang
tuc va » truc va, tuc xa, duc va
luc va » duc va, loc va
x hoi » xa hoi, o hoi, x ho

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: te sach y nang x hoi. thien van cau ((luc va) OR (((tuc va) OR (thuc va)))) hanh dao cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang x hoi. thien van cau ((luc va) or (((tuc va) OR (thuc va)))) hanh dao cua triet~".
• Adding a wildcard symbol may retrieve word variants: te sach y nang x hoi. thien van cau ((luc va) or (((tuc va) OR (thuc va)))) hanh dao cua triet*.
