Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, thien anh, thien danh
thanh tung » thanh cong
tranh luan » trinh luan, trinh luat, doanh luan
hieu manh » chieu xanh, hieu nganh, dieu hanh
cong cong » cong dong, dung cong, dang cong
van tranh » van thanh, van ranh, can tranh
tung cua » trung cua, tuong cua, dung cua

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: hoc ((thieu xanh) OR (hieu manh)) - thanh tung cua ((cong cong) OR (trong cong)) van tranh luan~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu xanh) or (hieu manh)) - thanh tung cua ((cong cong) OR (trong cong)) van tranh luan~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu xanh) or (hieu manh)) - thanh tung cua ((cong cong) OR (trong cong)) van tranh luan*.
