Perhaps you should try some spelling variations:
tranh luan » trinh luan, trinh luat, tang luan
doanh luan » doanh nhan
nhung cong » dung cong, thong cong, hang cong
chau tinh » cuu tinh, ha tinh, cac tinh
cua tinh » cua sinh, va tinh, ha tinh
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan tap » toan ban

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: ho ((chau tinh) OR (cua tinh)) - hanh ((tranh luan) OR (doanh luan)) nhung cong dan toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chau tinh) or (cua tinh)) - hanh ((tranh luan) OR (doanh luan)) nhung cong dan toan tap~".
• Adding a wildcard symbol may retrieve word variants: ho ((chau tinh) or (cua tinh)) - hanh ((tranh luan) OR (doanh luan)) nhung cong dan toan tap*.
