Perhaps you should try some spelling variations:
hien nhanh » hien hanh, thien thanh, tien thanh
canh doanh » hanh doanh, chinh doanh, doanh doanh
doanh luan » doanh nhan
hung huong » nhung huong, hung vuong, dung huong
hien xanh » hien hanh, chieu xanh, hien khanh
luan hung » luan chung, lan hung, luan ung
dan toan » van toan, dan than, manh toan
toan cao » toan ban, toan tap

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien xanh) OR (hien nhanh)) - canh doanh luan hung huong dan toan cao~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien xanh) OR (hien nhanh)) - canh doanh luan hung huong dan toan cao*.
