Perhaps you should try some spelling variations:
hieu va » lieu va, hieu qua
cam tuc » cam xuc, cam tu, nam thuc
danh di » danh du, danh dien, danh gia
xanh di » vanh dai, xanh tai
cuu tre » cua tre, cau tren, cau treo
vu sac » vu sach, vu san, va sac
sac ky » cac ky, sai ky
va cam » va cham, va cac, va cao
tuc va » thuc va, truc va, tuc xa

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: vu sac ky nang ((x ho) or (xa hoi)). hieu va cam tuc va ((danh di) OR (xanh di)) cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sac ky nang ((x ho) OR (xa hoi)). hieu va cam tuc va ((danh di) OR (xanh di)) cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sac ky nang ((x ho) or (xa hoi)). hieu va cam tuc va ((danh di) OR (xanh di)) cuu tre*".
