Perhaps you should try some spelling variations:
chinh doanh » kinh doanh
doanh luan » doanh nhan
hien xanh » hien hanh, hien nhanh, chieu xanh
han duong » van duong, thanh duong, phan xuong
hai duong » dai cuong, hai phong
than cau » toan cau, phan cau, than cap
va than » va thanh, van than, va phan

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

• Performing a fuzzy search may retrieve terms with similar spellings: hoc hien xanh - chinh doanh luan ((han duong) OR (hai duong)) va than cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien xanh - chinh doanh luan ((han duong) OR (hai duong)) va than cau*".
