nang xa » nang x, lang xa, nang ma
va tham » van tham, va cham, va thuat
va dinh » van dinh, va kinh, va tinh

cua tre » cua te, cuu tre, dua tren

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu van ky nang xa hoi. hieu ((va tham) OR (va thanh)) luc va dinh vi ((cua tre) or (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu van ky nang xa hoi. hieu ((va tham) OR (va thanh)) luc va dinh vi ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu van ky nang xa hoi. hieu ((va tham) OR (va thanh)) luc va dinh vi ((cua tre) or (cua triet))".
• Adding a wildcard symbol may retrieve word variants: tu van ky nang xa hoi. hieu ((va tham) OR (va thanh)) luc va dinh vi ((cua tre) or (cua triet))*.
