Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hieu van » hieu va, thien van, lieu va
van cham » van chat, van tham, va cham
te sach » toc sach
lang xa » lang ha, dang xay, lang van
danh di » danh du, xanh di, danh dien
y lang » o lang, _ lang, tay lang
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: te sach y lang xa hoi. hieu van cham ((duc va) OR (tuc xa)) danh di cua triet~.
• Adding a wildcard symbol may retrieve word variants: te sach y lang xa hoi. hieu van cham ((duc va) or (tuc xa)) danh di cua triet*.
