Perhaps you should try some spelling variations:
doanh thanh » danh thanh, doanh nhan, dinh thanh
thanh tieng » hanh tieng, thanh tien, thanh tung
hang khoa » dung khoa
tieu phan » lieu phan, tieu nhan, tieu chuan
phan kinh » than kinh, phan dinh, phan minh
lien ket » thien ket
qua tieu » luan tieu

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (ngan OR nganh) hang khoa ((luan ket) OR (lien ket)) qua tieu phan kinh doanh thanh tieng~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(ngan or nganh) hang khoa ((luan ket) OR (lien ket)) qua tieu phan kinh doanh thanh tieng~".
• Adding a wildcard symbol may retrieve word variants: (ngan or nganh) hang khoa ((luan ket) OR (lien ket)) qua tieu phan kinh doanh thanh tieng*.
