Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, chau tinh, kieu tinh
lieu tinh » trieu tinh, diep tinh, bien tinh
tranh cua » doanh cua, manh cua
cua nhung » va nhung
cong dan » cong tan, huong dan, cong dong
cong san » cong tac
chan cau » phan cau, can cau, chinh cau

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 ((chieu tinh) OR (lieu tinh)) - canh tranh cua nhung ((cong dan) OR (cong san)) chan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu tinh) or (lieu tinh)) - canh tranh cua nhung ((cong dan) OR (cong san)) chan cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu tinh) or (lieu tinh)) - canh tranh cua nhung ((cong dan) OR (cong san)) chan cau*.
