Perhaps you should try some spelling variations:
thanh trung » thanh tung
theo chieu » theo tieu, ho chieu, theo chu
chieu xanh » chieu sach, chieu sang, chieu tinh
cap duong » cac duong, cap dung, canh duong
cau duong » hai duong, con duong, van duong
cong tan » cong tac, cong thanh, cong ty
cong san » cong tac

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 trung ((cap duong) or (cau duong)) ((cong tan) OR (cong san)) van ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu xanh - thanh trung ((cap duong) OR (cau duong)) ((cong tan) OR (cong san)) van ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu xanh - thanh trung ((cap duong) or (cau duong)) ((cong tan) OR (cong san)) van ban*".
