Perhaps you should try some spelling variations:
van hanh » van thanh, ban hanh, van anh
xuc van » duc van, luc van, vuc van
sang ky » sang kyo, dang ky, tang ky
lang xa » lang ha, dang xay, lang van
cac xuc » cam xuc, cac nuoc, chat xuc
dan ky » van ky
di su » doi su, da su, de su
ki su » ky su

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

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