Perhaps you should try some spelling variations:
doanh hoan » doanh doanh, doanh khoa, doanh nhan
dung khai » dung hai, dang khai, dung khi
khai luan » khau luan, khai tuan, thai luan
tieu tham » lieu tham, hien tham, hieu pham
ban dung » van dung, dan dung, tan dung
luan ket » lien ket
tieu thu » trieu thi, tieu su
thien » thieu, tien, hien

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: "ban dung khai luan ket qua ((tieu tham) OR (tieu thu)) kinh doanh hoan thien~".
• Adding a wildcard symbol may retrieve word variants: ban dung khai luan ket qua ((tieu tham) OR (tieu thu)) kinh doanh hoan thien*.
