tang ma » mang may, tang van
hieu ve » hieu va, hieu van
te sac » te sach, te cac, te san
xuc va » duc va, tuc va, luc va

ve cam » ve cham, ve cac, va cam

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sac ky ((tang ma) or (nang cao)) hoi. hieu ve cam xuc va thanh doi ((cua triet) OR (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky ((tang ma) OR (nang cao)) hoi. hieu ve cam xuc va thanh doi ((cua triet) OR (su triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky ((tang ma) or (nang cao)) hoi. hieu ve cam xuc va thanh doi ((cua triet) OR (su triet))".
• Adding a wildcard symbol may retrieve word variants: te sac ky ((tang ma) or (nang cao)) hoi. hieu ve cam xuc va thanh doi ((cua triet) OR (su triet))*.
