Perhaps you should try some spelling variations:
lang xa » lang ha, dang xay, lang van
hieu va » lieu va, hieu qua
cao xuc » cam xuc, cao duc, cao suc
va hang » van hang, va nang, va lang
tai cua » thai cua, tai cuc, dai cua
sac ky » sai ky
va cao » va cac, va co, va dao
xuc va » duc va, tuc va, luc 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: tu ((sac ky) OR (cac ky)) lang xa hoi. hieu va cao xuc va hang ((tai cua) OR (tri cua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sac ky) OR (cac ky)) lang xa hoi. hieu va cao xuc va hang ((tai cua) or (tri cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: tu ((sac ky) OR (cac ky)) lang xa hoi. hieu va cao xuc va hang ((tai cua) or (tri cua)) tre*.
