nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua

cua tre » cua te, cua triet, dua tren
va hanh » van hanh, va thanh, ban hanh

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

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