cua tinh » cua sinh, va tinh, ha tinh
cam luc » cam xuc, cau luc
hanh va » hang va, hanh vi

hieu ve » hieu van
dang ma » dang mau, dang mam, dang mat
ky dang » ky nang, ky danh
sac ky » cac ky, sai ky
luc va » duc va, tuc va, loc va
ma hoi » mai hoi, xa hoi, ma hoa
te sac » te sach, te cac, te san

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 sac ky dang ma hoi. ((hieu ve) OR (hieu va)) cam luc va hanh va ((chua tinh) OR (cua tinh))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky dang ma hoi. ((hieu ve) or (hieu va)) cam luc va hanh va ((chua tinh) OR (cua tinh))~".
• Adding a wildcard symbol may retrieve word variants: te sac ky dang ma hoi. ((hieu ve) or (hieu va)) cam luc va hanh va ((chua tinh) OR (cua tinh))*.
