Perhaps you should try some spelling variations:
cao suc » cao su, cao duc
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
hieu va » lieu va, hieu qua
tai cua » thai cua, tai cuc, dai cua
cao xuc » cam xuc, cao duc, chat xuc
va hang » van hang, va nang, va lang
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky

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 lang xa hoi. hieu va ((cao xuc) OR (cao suc)) va hang ((tai cua) OR (tri cua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky lang xa hoi. hieu va ((cao xuc) OR (cao suc)) va hang ((tai cua) or (tri cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky lang xa hoi. hieu va ((cao xuc) OR (cao suc)) va hang ((tai cua) or (tri cua)) tre*.
