Perhaps you should try some spelling variations:
dinh doanh » kinh doanh, chinh doanh, doanh doanh
minh doanh » kinh doanh, minh danh, minh doan
hoan thieu » hoan thien, hoang trieu, hoc thieu
hang khoa » dung khoa
thiet tri » thiet bi, thien tai, thiet hai
ban hang » ngan hang
luan ket » lien ket
ket luan » ket qua, te luan, dat luan

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 hang khoa luan ket luan thiet tri ((dinh doanh) OR (minh doanh)) hoan thieu~".
• Adding a wildcard symbol may retrieve word variants: ban hang khoa luan ket luan thiet tri ((dinh doanh) OR (minh doanh)) hoan thieu*.
