Perhaps you should try some spelling variations:
hieu van » thien van, lieu va
ve triet » va trien, su triet
te sach » toc sach
sach ky » sac ky, sach y, sach ty
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
hieu va » lieu va, hieu qua
va hanh » van hanh, va thanh, va danh
hanh ve » hanh vi, hanh va, hanh kem
xuc va » duc va, tuc va, luc va
ve ve » de ve, va ve, ke ve

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky lang xa hoi. ((((hieu ve) OR (hieu van))) or (hieu va)) cam xuc va hanh ve ve triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky lang xa hoi. ((((hieu ve) OR (hieu van))) OR (hieu va)) cam xuc va hanh ve ve triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky lang xa hoi. ((((hieu ve) OR (hieu van))) or (hieu va)) cam xuc va hanh ve ve triet".
• Adding a wildcard symbol may retrieve word variants: te sach ky lang xa hoi. ((((hieu ve) OR (hieu van))) or (hieu va)) cam xuc va hanh ve ve triet*.
