Perhaps you should try some spelling variations:
thien van » thi van
cua triet » su triet, va triet
cua viet » ca viet, hoa viet, cua vat
nang xa » nang x, lang xa, nang ma
van lam » van nam
dinh vi » dinh ve, dinh viet, dinh tri
te sai » te tai, te bai, te lai
sai ky » sac ky
xuc va » tuc va, luc va, xac va

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

• If you are trying to use Boolean operators, they must be ALL CAPS: te sai ky nang xa hoi. thien van lam ((xuc va) OR (duc va)) dinh vi ((cua triet) OR (cua viet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sai ky nang xa hoi. thien van lam ((xuc va) or (duc va)) dinh vi ((cua triet) OR (cua viet))~".
• Adding a wildcard symbol may retrieve word variants: te sai ky nang xa hoi. thien van lam ((xuc va) or (duc va)) dinh vi ((cua triet) OR (cua viet))*.
