hieu va » lieu va, hieu qua
va tham » van tham, va cham, va thanh
va hanh » van hanh, va thanh, va danh
cua tre » cuu tre, cua triet, dua tren
te cac » tu cac, ve cac, te cao

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

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