Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
va hanh » van hanh, va thanh, va danh
cua tre » cua te, cuu tre, dua tren
cam tu » cam thu, nam tu, tam tu
dam tu » nam tu, tam tu, dam thuc

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

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