Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
hanh trang » thanh trung, hanh trinh, minh trang
cua nhung » va nhung
yen tinh » tuyen tinh
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan tap » toan ban
cot » cost

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