Perhaps you should try some spelling variations:
cua viet » hoa viet, cua vat, cua dieu
nang xa » nang x, lang xa, nang ma
ve cham » va cham, ve chat, vu cham
va hanh » van hanh, va thanh, va danh
ca viet » va viet, co viet, hoa viet
ve cai » va cai, ve cac, ve tai
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: tu cac ky nang xa hoi. hieu ((ve cai) or (ve cham)) loc va hanh vi ((cua viet) OR (ca viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky nang xa hoi. hieu ((ve cai) OR (ve cham)) loc va hanh vi ((cua viet) OR (ca viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky nang xa hoi. hieu ((ve cai) or (ve cham)) loc va hanh vi ((cua viet) OR (ca viet))".
• Adding a wildcard symbol may retrieve word variants: tu cac ky nang xa hoi. hieu ((ve cai) or (ve cham)) loc va hanh vi ((cua viet) OR (ca viet))*.
