Perhaps you should try some spelling variations:
hanh truong » hanh trong, anh truong, manh truong
chiet tach » chieu sach
hieu manh » chieu xanh, hieu nganh, dieu hanh
van dung » van dong, xay dung, tin dung
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan ban » van ban
va dung » va duong, vat dung, va ung

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

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