Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hieu van » hieu va, thien van, lieu va
va thanh » gia thanh, ban thanh, va tinh
thanh vi » hanh vi, thanh va, thanh ve
lang xa » lang ha, dang xay, lang van
van lam » van nam
lam xuc » cam xuc, lam duoc
cua tre » cua te, cuu tre, dua tren
san ky » sang ky, dan ky, ban ky
xuc va » duc va, tuc 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 ((san ky) or (van ky)) lang xa hoi. hieu van lam xuc va thanh vi ((cua tre) OR (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((san ky) OR (van ky)) lang xa hoi. hieu van lam xuc va thanh vi ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((san ky) or (van ky)) lang xa hoi. hieu van lam xuc va thanh vi ((cua tre) OR (cua triet))".
• Adding a wildcard symbol may retrieve word variants: tu ((san ky) or (van ky)) lang xa hoi. hieu van lam xuc va thanh vi ((cua tre) OR (cua triet))*.
