Perhaps you should try some spelling variations:
luat hoi » luat moi, luat so, luat dai
hieu ve » hieu va, hieu van
ky dang » ky nang, ky danh
dinh vi » dinh ve, dinh viet, dinh tri
lai hoi » dai hoi, lai hoa, lai roi
danh vi » hanh vi, danh di, danh va
tu sac » tu sach, tu cac, tu san
xuc va » duc va, tuc va, luc va
ve cam » ve cham, ve cac, va cam
sac ky » cac ky, sai ky
cua te » cua tu

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky dang ((luat hoi) or (lai hoi)). hieu ve cam xuc va ((danh vi) OR (dinh vi)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky dang ((luat hoi) OR (lai hoi)). hieu ve cam xuc va ((danh vi) OR (dinh vi)) cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky dang ((luat hoi) or (lai hoi)). hieu ve cam xuc va ((danh vi) OR (dinh vi)) cua te*".
