Perhaps you should try some spelling variations:
theo chiet » theo chieu, thep thiet
chiet tach » chieu sach
nhung cong » dung cong, thong cong, hang cong
cong doan » cong dan, cong hoan, dong doanh
doan phan » doanh phan, toan phan, dan phan
van quan » van ban
phan dau » phan tu, hang dau

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 - canh ((ban cua) or (((ban quan) OR (van quan)))) nhung cong doan phan dau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo chiet tach - canh ((ban cua) OR (((ban quan) OR (van quan)))) nhung cong doan phan dau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chiet tach - canh ((ban cua) or (((ban quan) OR (van quan)))) nhung cong doan phan dau*".
