va dinh » van dinh, va kinh, va tinh
nang xa » lang xa, nang ma, mang xa

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: tu ((san ky) or (dan ky)) ((nang xa) OR (nang x)) hoi. hieu ve cam xuc va dinh tai cac viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((san ky) OR (dan ky)) ((nang xa) OR (nang x)) hoi. hieu ve cam xuc va dinh tai cac viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((san ky) or (dan ky)) ((nang xa) OR (nang x)) hoi. hieu ve cam xuc va dinh tai cac viet".
• Adding a wildcard symbol may retrieve word variants: tu ((san ky) or (dan ky)) ((nang xa) OR (nang x)) hoi. hieu ve cam xuc va dinh tai cac viet*.
