nang xa » nang x, lang xa, nang ma
ve cham » va cham, ve chat, vu cham

dinh vi » dinh ve, dinh viet, dinh tri
sac ky » cac ky, sai ky
va cam » va cham, va cac, va cao
loc va » hoc 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: thuat sac ky nang xa hoi. hieu ((va cam) or (ve cham)) loc va ((danh vi) OR (dinh vi)) cua vat~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sac ky nang xa hoi. hieu ((va cam) OR (ve cham)) loc va ((danh vi) OR (dinh vi)) cua vat.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sac ky nang xa hoi. hieu ((va cam) or (ve cham)) loc va ((danh vi) OR (dinh vi)) cua vat".
• Adding a wildcard symbol may retrieve word variants: thuat sac ky nang xa hoi. hieu ((va cam) or (ve cham)) loc va ((danh vi) OR (dinh vi)) cua vat*.
