Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
lang van » dang van, hoang van, giang van
tang van » dang van, hoang van, trong van
pham huu » pham duc, pham duy, phan huy
te sach » toc sach
hieu ve » hieu va, hieu van
ve pham » vi pham, v pham, ve phan
va hanh » van hanh, va thanh, va danh
cua tre » cua te, cuu tre, dua tren
huu va » cuu va, tuu 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: te sach _ ((lang van) OR (tang van)) hoi. hieu ve pham huu va hanh vi ((cua tre) OR (cua triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach _ ((lang van) OR (tang van)) hoi. hieu ve pham huu va hanh vi ((cua tre) or (cua triet))~".
• Adding a wildcard symbol may retrieve word variants: te sach _ ((lang van) OR (tang van)) hoi. hieu ve pham huu va hanh vi ((cua tre) or (cua triet))*.
