Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thanh ve » hanh ve, thanh va, thanh vien
kho tang » cao tang
thanh vi » hanh vi, thanh va, nhanh vi
ky tang » ky nang, ky dang, ky trong
hieu ve » hieu va, hieu van
dam tu » nam tu, cam tu, tam tu
ma hoi » mai hoi, xa hoi, ma hoa
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) OR (kho tang)) ma 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) OR (kho tang)) ma 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) OR (kho tang)) ma hoi. hieu ve dam tu va ((thanh vi) or (thanh ve)) cua triet*.
