Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
ky lang » ky dang, ky tang, tay lang
nam xuc » cam xuc, nam xua, nam thuc
va hanh » van hanh, va thanh, va danh
te sac » te sach, te cac, te san
xuc va » duc va, tuc va, luc va
ve ve » de ve, ke ve, ve ke
va ve » va de, va le, va vi

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