Perhaps you should try some spelling variations:
hanh dung » thanh dung, anh dung, manh dung
hanh dong » anh dong, ha dong
luan cong » luat cong, luong cong, luan chung
cong cong » cong dong, trong cong, dung cong
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan ban » van ban
ha tinh » va tinh, may tinh

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

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