Perhaps you should try some spelling variations:
dinh tai » dinh toai, dinh tri, dinh thi
cuc viet » chuc viet, tuc viet, cua viet
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
thuc va » thuc vat, thuc dan, thuc day
tu san » thu san, tu ban, tu can
san ky » sang ky, van ky, dan ky
ve cam » ve cham, ve cac, va cam
tuc va » truc va, tuc xa, thuc vat

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 nang xa hoi. hieu ve cam ((((tuc va) or (duc va))) or (thuc va)) dinh tai cuc viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu san ky nang xa hoi. hieu ve cam ((((tuc va) OR (duc va))) OR (thuc va)) dinh tai cuc viet.
• Adding a wildcard symbol may retrieve word variants: tu san ky nang xa hoi. hieu ve cam ((((tuc va) or (duc va))) or (thuc va)) dinh tai cuc viet*.
