Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hang di » hang doi, hang vi, hang dien
hanh di » hanh vi, hanh de, danh di
xuc van » duc van, luc van, vuc van
hieu va » lieu va, hieu qua
cac xuc » cam xuc, cac nuoc, chat xuc
lang xa » lang ha, dang xay, lang van
san ky » sang ky, van ky, ban ky
dan ky » van ky

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: tu ((san ky) or (dan ky)) lang xa hoi. hieu va cac xuc van ((hanh di) OR (hang di)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((san ky) OR (dan ky)) lang xa hoi. hieu va cac xuc van ((hanh di) OR (hang di)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((san ky) or (dan ky)) lang xa hoi. hieu va cac xuc van ((hanh di) OR (hang di)) cua triet".
• Adding a wildcard symbol may retrieve word variants: tu ((san ky) or (dan ky)) lang xa hoi. hieu va cac xuc van ((hanh di) OR (hang di)) cua triet*.
