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