Perhaps you should try some spelling variations:
kho tang » cao tang
hanh tai » thanh tai, hang tai, han tai
cua tre » cua te, cuu tre, cua triet
tang xa » trang xa, tang ma, lang xa
hieu va » lieu va, hieu qua
cuc tre » duc tre, cuu tre, cuc thue
sai kho » dai kho, tai khoa, dai khoa
tu sai » tu bai, tu san, tu cai
loc va » hoc va
va cam » va cham, va cac, va cao
luc va » duc va, tuc 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 sai kho tang xa hoi. hieu va cam ((luc va) OR (loc va)) hanh tai ((cuc tre) OR (cua tre))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sai kho tang xa hoi. hieu va cam ((luc va) or (loc va)) hanh tai ((cuc tre) OR (cua tre))~".
• Adding a wildcard symbol may retrieve word variants: tu sai kho tang xa hoi. hieu va cam ((luc va) or (loc va)) hanh tai ((cuc tre) OR (cua tre))*.
