Perhaps you should try some spelling variations:
cua viet » ca viet, hoa viet, cua vat
cham xuc » cam xuc, chat xuc, cham soc
hanh de » hanh ve, hanh kem
hanh di » hanh vi, hang di, danh di
xuc van » duc van, luc van, vuc van
va cham » va chat, va tham
hieu va » lieu va, hieu qua
lang xa » lang ha, dang xay, lang van
sang ky » sang kyo, dang ky, tang ky
san ky » van ky, dan ky, ban 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 (sang ky)) lang xa hoi. hieu va cham xuc van ((hanh di) or (hanh de)) cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((san ky) OR (sang ky)) lang xa hoi. hieu va cham xuc van ((hanh di) OR (hanh de)) cua viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((san ky) OR (sang ky)) lang xa hoi. hieu va cham xuc van ((hanh di) or (hanh de)) cua viet".
• Adding a wildcard symbol may retrieve word variants: tu ((san ky) OR (sang ky)) lang xa hoi. hieu va cham xuc van ((hanh di) or (hanh de)) cua viet*.
