Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
thanh tung » thanh cong
hieu manh » chieu xanh, hieu nganh, dieu hanh
cong danh » cuong danh, cong thanh, cong khanh
va thong » va thuong, va phuong, he thong
cong dan » cong san, cong tan, huong dan
toan cau » toan cao, toan ban, toan tap
tung va » trung va, tuong va, dung va

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 ((hieu manh) OR (chieu tinh)) - thanh tung va thong ((cong danh) OR (cong dan)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((hieu manh) or (chieu tinh)) - thanh tung va thong ((cong danh) OR (cong dan)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((hieu manh) or (chieu tinh)) - thanh tung va thong ((cong danh) OR (cong dan)) toan cau*.
