Perhaps you should try some spelling variations:
vien cua » viec cua, dien cua, tien cua
thu xac » thau xay
cao hoi » cau hoi, co hoi, cao hoc
hieu ve » hieu van
hieu va » lieu va, hieu qua
cao suc » cao su
cao duc » dao duc, giao duc, tao duoc
va nhan » van nhan, ca nhan, va phan
xac ky » cac ky, sac ky, bac ky
cua te » cua tu

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

• If you are trying to use Boolean operators, they must be ALL CAPS: thu xac ky nang cao hoi. ((hieu ve) OR (hieu va)) ((cao suc) OR (cao duc)) va nhan vien cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu xac ky nang cao hoi. ((hieu ve) or (hieu va)) ((cao suc) OR (cao duc)) va nhan vien cua te~".
• Adding a wildcard symbol may retrieve word variants: thu xac ky nang cao hoi. ((hieu ve) or (hieu va)) ((cao suc) OR (cao duc)) va nhan vien cua te*.
