Perhaps you should try some spelling variations:
thanh cuong » thanh chuong, thanh cong, thanh huong
thanh luong » thanh huong, thanh long, thanh duong
theo chieu » theo tieu, ho chieu, theo chu
chieu xanh » chieu sach, chieu sang, chieu tinh
dang cong » dung cong
van dang » van dong, van dung, van nang
cong tan » cong tac, cong san, cong thanh
toan cao » toan tap
toan ban » van ban

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

• Performing a fuzzy search may retrieve terms with similar spellings: theo chieu xanh - ((thanh luong) OR (thanh cuong)) van dang cong tan ((toan cao) or (toan ban))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu xanh - ((thanh luong) OR (thanh cuong)) van dang cong tan ((toan cao) OR (toan ban))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu xanh - ((thanh luong) OR (thanh cuong)) van dang cong tan ((toan cao) or (toan ban))*".
