Perhaps you should try some spelling variations:
dung khai » dung hai, dang khai, dung khi
khai luan » khau luan, khai tuan, thai luan
tieu tham » lieu tham, tieu thu, hien tham
tham kinh » than kinh, tham dinh, thao kinh
doanh han » doanh hoan, doanh phan, doanh ban
ban dung » van dung, dan dung, tan dung
luan ket » lien ket
qua tieu » luan tieu

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