Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, hieu ve
ky dang » ky nang, ky danh
dang xa » dang xay, lang xa, dang ha
nam xuc » cam xuc, nam xua, nam thuc
va hanh » van hanh, va thanh, va danh
te sac » te sach, te cac, te san
sac ky » cac ky, sai ky
xuc va » duc va, tuc va, luc va
ve ve » va ve, ke ve, ve ke

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

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