Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hieu van » hieu va, thien van, hieu ve
ky lang » ky nang, ky dang, tay lang
ky tang » ky nang, ky dang, kho tang
va hanh » van hanh, va thanh, va danh
hanh di » hanh vi, hanh de, hang di
tu dan » tuc dan, tu ban, cu dan
xuc va » duc va, tuc va, luc va
di cua » dai cua, doi cua, de cua

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 dan ((ky lang) OR (ky tang)) xa hoi. ((hieu van) OR (lieu va)) cam xuc va hanh di cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu dan ((ky lang) or (ky tang)) xa hoi. ((hieu van) OR (lieu va)) cam xuc va hanh di cua triet~".
• Adding a wildcard symbol may retrieve word variants: tu dan ((ky lang) or (ky tang)) xa hoi. ((hieu van) OR (lieu va)) cam xuc va hanh di cua triet*.
