Perhaps you should try some spelling variations:
thong cong » trong cong, tong cong, thong thong
theo bien » thieu bien, theo tieu, che bien
bien tinh » bi tinh, yen tinh, diep tinh
cua thong » cua thuong, cua khong, cua tong
anh tang » anh dang, anh nang, anh sang
anh bang » anh hoang, anh quang, tinh bang
cong tac » cong ty
toan tai » toan tap, doanh tai, toan ban
toan cao » toan ban, toan tap

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: theo bien tinh - ((anh tang) OR (anh bang)) cua thong cong tac ((toan tai) OR (toan cao))~.
• Adding a wildcard symbol may retrieve word variants: theo bien tinh - ((anh tang) or (anh bang)) cua thong cong tac ((toan tai) or (toan cao))*.
