Perhaps you should try some spelling variations:
chiet tach » chieu sach
nhung cong » dung cong, thong cong, nhung don
hanh dung » thanh dung, anh dung, hanh dong
hang cong » dang cong, hang nong, bang cong
dung cua » dung luan, dung cho
dan han » dan chan, dan than, dan hanh
han tap » han tai, toan tap, nhan tai

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

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