Perhaps you should try some spelling variations:
chieu tinh » lieu tinh, chau tinh, kieu tinh
hanh dung » thanh dung, anh dung, hanh dong
luan hang » luan nang, luan han, luan tang
luan hung » luan chung, lan hung, luan ung
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan cau » toan cao, toan ban, toan tap

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ho ((chieu tinh) or (trieu tinh)) - hanh dung ((luan hang) OR (luan hung)) cong dan toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu tinh) OR (trieu tinh)) - hanh dung ((luan hang) OR (luan hung)) cong dan toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu tinh) or (trieu tinh)) - hanh dung ((luan hang) OR (luan hung)) cong dan toan cau".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu tinh) or (trieu tinh)) - hanh dung ((luan hang) OR (luan hung)) cong dan toan cau*.
