Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
danh sai » dung sai, danh bat, danh dau
danh dai » danh dau, danh di, vanh dai
hieu van » hieu va, thien van, lieu va
nam xuc » cam xuc, nam xua, nam thuc
lang xa » lang ha, dang xay, lang van
sang ky » sang kyo, dang ky, tang ky
dan ky » van ky
xuc va » duc va, tuc va, luc va

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: tu ((dan ky) or (sang ky)) lang xa hoi. hieu van nam xuc va ((danh dai) OR (danh sai)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((dan ky) OR (sang ky)) lang xa hoi. hieu van nam xuc va ((danh dai) OR (danh sai)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((dan ky) or (sang ky)) lang xa hoi. hieu van nam xuc va ((danh dai) OR (danh sai)) cua triet".
• Adding a wildcard symbol may retrieve word variants: tu ((dan ky) or (sang ky)) lang xa hoi. hieu van nam xuc va ((danh dai) OR (danh sai)) cua triet*.
