Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
van hanh » van thanh, ban hanh, van anh
cham xuc » cam xuc, chat xuc, pham duc
dang xay » dang van, van xay
hanh di » hanh vi, hanh de, hang di
lang xa » lang ha, lang van
san ky » sang ky, van ky, dan ky
di cua » dai cua, doi cua, de cua
tu san » thu san, tu ban, tu can

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