Perhaps you should try some spelling variations:
doanh hoan » doanh doanh, doanh khoa, doanh nhan
hang khoa » dung khoa
hoan hien » hoan thien, han hien, hoa hien
ket luan » ket qua, te luan, ket doan
dat luan » dan luan, dau luan, dat quang
thi kinh » tri kinh, thi minh, thi hinh
ngan » nganh, nhan

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: "ngan hang khoa luan ((ket luan) OR (dat luan)) trieu thi kinh doanh hoan hien~".
• Adding a wildcard symbol may retrieve word variants: ngan hang khoa luan ((ket luan) OR (dat luan)) trieu thi kinh doanh hoan hien*.
