Perhaps you should try some spelling variations:
hanh tranh » canh tranh, hanh trinh, hanh trang
tranh luan » trinh luan, trinh luat, doanh luan
kieu tinh » lieu tinh, diep tinh, bien tinh
luan dang » luan nang, luan danh, luan dong
dang cong » dung cong
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan cau » toan cao, toan ban, toan tap

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: theo ((kieu tinh) OR (trieu tinh)) - hanh tranh luan dang cong dan toan cau~.
• Adding a wildcard symbol may retrieve word variants: theo ((kieu tinh) or (trieu tinh)) - hanh tranh luan dang cong dan toan cau*.
