Perhaps you should try some spelling variations:
cuu tre » cau tren, cau treo
cac xuc » cam xuc, cac nuoc, chat xuc
ky tang » ky nang, ky dang, kho tang
cua tre » cua te, cua triet, dua tren
danh di » danh du, xanh di, danh dien
hieu ve » hieu va, hieu van
va danh » va dinh, va dan, va hanh
vu sac » vu sach, vu san, va sac
xuc va » duc va, tuc va, luc va
sac ky » cac ky, sai ky
ma hoi » mai hoi, xa hoi, me hoi
ve cac » va cac, vien cac

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: vu sac ky tang ((ma hoi) OR (ma hoa)). hieu ve cac xuc va danh di ((cua tre) OR (cuu tre))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sac ky tang ((ma hoi) or (ma hoa)). hieu ve cac xuc va danh di ((cua tre) OR (cuu tre))~".
• Adding a wildcard symbol may retrieve word variants: vu sac ky tang ((ma hoi) or (ma hoa)). hieu ve cac xuc va danh di ((cua tre) OR (cuu tre))*.
