Perhaps you should try some spelling variations:
thanh trung » thanh tung
chieu xanh » chieu sach, chieu sang, chieu tinh
nhung cong » dung cong, thong cong, hang cong
tam nhung » tham nhung, cam nhung, nam nhung
cong dan » cong san, cong tan, huong dan
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: ho ((chinh sach) or (chieu xanh)) - thanh trung tam nhung cong dan ((toan cao) OR (toan ban))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chinh sach) OR (chieu xanh)) - thanh trung tam nhung cong dan ((toan cao) OR (toan ban))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chinh sach) or (chieu xanh)) - thanh trung tam nhung cong dan ((toan cao) OR (toan ban))*".
