Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thanh ve » hanh ve, thanh va, thanh vien
thanh vi » hanh vi, thanh va, nhanh vi
ky tang » ky nang, ky dang, kho tang
hieu ve » hieu va, hieu van
mai hoi » mai khoi, dai hoi, lai hoi
dam tu » nam tu, cam tu, tam tu
ma hoi » xa hoi, ma hoa, 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 cac ky tang ((ma hoi) OR (mai hoi)). hieu ve dam tu va ((thanh vi) OR (thanh ve)) cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky tang ((ma hoi) OR (mai hoi)). hieu ve dam tu va ((thanh vi) or (thanh ve)) cua triet~".
• Adding a wildcard symbol may retrieve word variants: tu cac ky tang ((ma hoi) OR (mai hoi)). hieu ve dam tu va ((thanh vi) or (thanh ve)) cua triet*.
