Perhaps you should try some spelling variations:
khong cong » thong cong, khong cang, chong cong
hieu manh » chieu xanh, hieu nganh, dieu hanh
trang cua » tranh cua, tang cua, trung cua
doanh cua » doanh luan
toc hieu » toc thieu, doc hieu, hoc thieu
cong tan » cong tac, cong san, cong thanh
toan cau » toan cao, toan tap, toan tai
toan ban » van ban

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: toc hieu manh - hanh ((trang cua) OR (doanh cua)) khong cong tan ((toan cau) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc hieu manh - hanh ((trang cua) or (doanh cua)) khong cong tan ((toan cau) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: toc hieu manh - hanh ((trang cua) or (doanh cua)) khong cong tan ((toan cau) OR (toan ban))*.
