Perhaps you should try some spelling variations:
cua triet » cua viet, su triet
thanh va » thanh van, hanh va, thanh ha
va triet » va thiet, va trien, ve triet
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
ve cham » va cham, ve chat, vu cham
tuc va » thuc va, truc va, tuc xa
luc va » duc va, loc 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 cham ((tuc va) or (luc va)) thanh va ((cua triet) OR (va triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky nang xa hoi. hieu ve cham ((tuc va) OR (luc va)) thanh va ((cua triet) OR (va triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky nang xa hoi. hieu ve cham ((tuc va) or (luc va)) thanh va ((cua triet) OR (va triet))".
• Adding a wildcard symbol may retrieve word variants: tu cac ky nang xa hoi. hieu ve cham ((tuc va) or (luc va)) thanh va ((cua triet) OR (va triet))*.
