dinh te » kinh te, dinh ve, dinh tu
te sach » toc sach
tu lang » cu lang, tu lanh, tu quang
xu lang » cu lang, xu dang, xu quang
hieu ve » hieu va, hieu van

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: te sach ((xu lang) OR (tu lang)) xa hoi. hieu ve cam xuc va ((dinh te) or (dich te)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((xu lang) OR (tu lang)) xa hoi. hieu ve cam xuc va ((dinh te) OR (dich te)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((xu lang) OR (tu lang)) xa hoi. hieu ve cam xuc va ((dinh te) or (dich te)) cua triet".
• Adding a wildcard symbol may retrieve word variants: te sach ((xu lang) OR (tu lang)) xa hoi. hieu ve cam xuc va ((dinh te) or (dich te)) cua triet*.
