Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hanh hoi » hanh thoi, hanh noi, hanh hoa
hoi cua » hoi chuc
duc ban » duc van, dua ban, duc man
hieu ve » hieu va, hieu van
tang xa » trang xa, tang ma, lang xa
ky tang » ky nang, ky dang, kho tang
ve cam » ve cham, ve cac, va cam
su can » su van, su cao, tu can
su cac » tu cac, su cao, eu cac

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: ((su cac) OR (su can)) ky tang xa hoi. hieu ve cam ((duc ban) OR (duc tan)) hanh hoi cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su cac) OR (su can)) ky tang xa hoi. hieu ve cam ((duc ban) or (duc tan)) hanh hoi cua triet~".
• Adding a wildcard symbol may retrieve word variants: ((su cac) OR (su can)) ky tang xa hoi. hieu ve cam ((duc ban) or (duc tan)) hanh hoi cua triet*.
