Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thien van » thi van
van cham » van chat, van tham, va cham
sach ty » sach y, sach tu, sach thu
nang xa » nang x, lang xa, nang ma
sach ky » sac ky, sach y, sach kem
hanh di » hanh vi, hanh de, hang di
soc va » loc va, doc va, goc va
di cua » dai cua, doi cua, de cua

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 ty)) nang xa hoi. thien van cham ((soc va) OR (hoc va)) hanh di cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) OR (sach ty)) nang xa hoi. thien van cham ((soc va) or (hoc va)) hanh di cua triet~".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) OR (sach ty)) nang xa hoi. thien van cham ((soc va) or (hoc va)) hanh di cua triet*.
