Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
nang xa » nang x, lang xa, nang ma
hieu ve » hieu van
hieu va » lieu va, hieu qua
va hanh » van hanh, va thanh, va danh
tu san » thu san, tu ban, vu san
tu can » tu ban, tu cac, thu canh
cam tu » cam thu, nam tu, dam tu
vi cua » vai cua, di 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 san) OR (tu can)) ky nang xa hoi. ((hieu ve) OR (hieu va)) cam tu va hanh vi cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu san) or (tu can)) ky nang xa hoi. ((hieu ve) OR (hieu va)) cam tu va hanh vi cua triet~".
• Adding a wildcard symbol may retrieve word variants: ((tu san) or (tu can)) ky nang xa hoi. ((hieu ve) OR (hieu va)) cam tu va hanh vi cua triet*.
