Perhaps you should try some spelling variations:
hien quan » thien quan, lien quan, vien quan
hanh doan » hanh doanh, thanh toan, thinh doan
va phuong » va thuong, cac phuong
va thong » va thuong, he thong, va cong
cong van » cong vang, cong san, song van
toan cau » toan ban, toan tap, toan tai
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: hoc hien quan - hanh doan ((va thong) OR (va phuong)) cong van ((toan cau) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien quan - hanh doan ((va thong) OR (va phuong)) cong van ((toan cau) or (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: hoc hien quan - hanh doan ((va thong) OR (va phuong)) cong van ((toan cau) or (toan cao))*.
