Perhaps you should try some spelling variations:
cua viet » hoa viet, cua vat, cua dieu
van hanh » van thanh, ban hanh, van anh
lang van » dang van, tang van, hoang van
ca viet » va viet, co viet, hoa viet
xuc van » duc van, luc van, vuc van
hieu va » lieu va, hieu qua
van hoi » van hoa, van hoc, van hoe
can ky » van ky, dan ky, tan ky
va cam » va cham, va cac, va cao
ban ky » van ky, dan 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 ((can ky) OR (ban ky)) lang van hoi. hieu va cam xuc van hanh vi ((cua viet) or (ca viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((can ky) OR (ban ky)) lang van hoi. hieu va cam xuc van hanh vi ((cua viet) OR (ca viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((can ky) OR (ban ky)) lang van hoi. hieu va cam xuc van hanh vi ((cua viet) or (ca viet))".
• Adding a wildcard symbol may retrieve word variants: tu ((can ky) OR (ban ky)) lang van hoi. hieu va cam xuc van hanh vi ((cua viet) or (ca viet))*.
