may hoi » may thoi, tay hoi, mai hoi
cau xuc » cam xuc, cau luc, cau truc
xuc van » duc van, luc van, vuc van
hanh va » hang va, hanh vi

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ty mang may hoi. ((hieu van) OR (lieu va)) cau xuc van ((thanh van) or (hanh va)) va triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty mang may hoi. ((hieu van) OR (lieu va)) cau xuc van ((thanh van) OR (hanh va)) va triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty mang may hoi. ((hieu van) OR (lieu va)) cau xuc van ((thanh van) or (hanh va)) va triet".
• Adding a wildcard symbol may retrieve word variants: tu sach ty mang may hoi. ((hieu van) OR (lieu va)) cau xuc van ((thanh van) or (hanh va)) va triet*.
