Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
doanh va » doan va, doanh tai, doanh cua
cuu tre » cau tren, cau treo
ky tang » ky nang, ky dang, kho tang
tang ma » mang may, tang van
van cac » van hac, van cau, van bac
cua tre » cua te, cua triet, dua tren
truc va » thuc va, thuc vat, trung va
te sai » te tai, te bai, te lai
sai ky » sac ky
tuc va » thuc va, tuc xa, duc 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: te sai ky tang ma hoa. hieu van cac ((tuc va) OR (truc va)) doanh va ((cua tre) OR (cuu tre))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sai ky tang ma hoa. hieu van cac ((tuc va) OR (truc va)) doanh va ((cua tre) or (cuu tre))~".
• Adding a wildcard symbol may retrieve word variants: te sai ky tang ma hoa. hieu van cac ((tuc va) OR (truc va)) doanh va ((cua tre) or (cuu tre))*.
