Perhaps you should try some spelling variations:
danh hoa » thanh hoa, khanh hoa, nganh hoa
hoa chuc » hoi chuc, hoc chuc, nhom chuc
vu sach » su sach, vu khach
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
chuc ke » thuc ke
va cam » va cham, va cac, va cao
tuc va » thuc va, truc va, duc va

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((vu sach) or (vu bach)) ky nang xa hoi. hieu va cam ((tuc va) OR (tuc xa)) danh hoa chuc ke~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (vu bach)) ky nang xa hoi. hieu va cam ((tuc va) OR (tuc xa)) danh hoa chuc ke.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) or (vu bach)) ky nang xa hoi. hieu va cam ((tuc va) OR (tuc xa)) danh hoa chuc ke".
• Adding a wildcard symbol may retrieve word variants: ((vu sach) or (vu bach)) ky nang xa hoi. hieu va cam ((tuc va) OR (tuc xa)) danh hoa chuc ke*.
