Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
su triet » su viet, su tien, ve triet
va thanh » gia thanh, ban thanh, va tinh
thanh vi » hanh vi, thanh va, thanh ve
ky sang » ky nang, ky dang, ky tang
hieu ve » hieu va, hieu van
tu sac » tu sach, tu cac, tu san
dam tu » nam tu, cam tu, tam tu
sac ky » cac ky, sai ky
ma hoi » mai hoi, xa hoi, me hoi
ve dam » ven dam, ke dam, va dam

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: tu sac ky sang ((ma hoi) OR (ma hoa)). hieu ve dam tu va thanh vi ((cua triet) OR (su triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky sang ((ma hoi) OR (ma hoa)). hieu ve dam tu va thanh vi ((cua triet) or (su triet))~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky sang ((ma hoi) OR (ma hoa)). hieu ve dam tu va thanh vi ((cua triet) or (su triet))*.
