Perhaps you should try some spelling variations:
sinh doanh » kinh doanh, sinh danh, minh doanh
trien nhan » trien nha, tri nhan, trien khai
doanh khoa » toan khoa
hang khoa » dung khoa
tieu nhan » tiep nhan, tieu chuan, thien nhan
khoa than » hoa thai, hoa tan, kho khan
ban hang » ngan hang
luan ket » lien ket

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 qua ((tieu nhan) OR (trien nhan)) sinh doanh khoa than~".
• Adding a wildcard symbol may retrieve word variants: ban hang khoa luan ket qua ((tieu nhan) OR (trien nhan)) sinh doanh khoa than*.
