Perhaps you should try some spelling variations:
cua triet » su triet, va triet
hieu van » hieu va, thien van, lieu va
cua viet » ca viet, hoa viet, cua vat
tuc dan » thuc dan, thuc day, tung dan
nang xa » nang x, lang xa, nang ma
cam luc » cau luc
va hanh » van hanh, va thanh, va danh
hanh va » hang va, hanh vi
dan ky » van ky

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

• Performing a fuzzy search may retrieve terms with similar spellings: tuc dan ky nang xa hoi. hieu van ((cam luc) or (cam xuc)) va hanh va ((cua triet) OR (cua viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tuc dan ky nang xa hoi. hieu van ((cam luc) OR (cam xuc)) va hanh va ((cua triet) OR (cua viet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tuc dan ky nang xa hoi. hieu van ((cam luc) or (cam xuc)) va hanh va ((cua triet) OR (cua viet))*".
