Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
lang xa » lang ha, dang xay, lang van
hieu va » lieu va, hieu qua
xuc van » luc van, xuc ban, thuc van
duc van » duc va, duc tan, duc manh
hanh di » hanh vi, hanh de, hang di
san ky » sang ky, van ky, ban ky
dan ky » van ky
va cam » va cham, va cac, va cao
di cua » dai cua, doi cua, de cua

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 cam ((xuc van) OR (duc van)) hanh 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 cam ((xuc van) OR (duc van)) hanh 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 cam ((xuc van) OR (duc van)) hanh di cua triet".
• Adding a wildcard symbol may retrieve word variants: tu ((san ky) or (dan ky)) lang xa hoi. hieu va cam ((xuc van) OR (duc van)) hanh di cua triet*.
