Perhaps you should try some spelling variations:
thieu tinh » trieu tinh, chieu tinh, thien tinh
doanh luan » doanh nhan
hoc thieu » toc thieu, hoc hien
hang cong » dang cong, hang nong, bang cong
dung cong » dung trong
tan toan » tan tran, tap toan, van toan
toan cau » 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 thieu tinh - hanh ((doanh cua) OR (doanh luan)) ((hang cong) OR (dung cong)) tan toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu tinh - hanh ((doanh cua) OR (doanh luan)) ((hang cong) or (dung cong)) tan toan cau~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu tinh - hanh ((doanh cua) OR (doanh luan)) ((hang cong) or (dung cong)) tan toan cau*.
