Perhaps you should try some spelling variations:
thanh tung » thanh cong
chi xanh » chi anh, chi danh, chi hanh
van dung » van dong, xay dung, tin dung
cong dan » cong tan, huong dan, cong dong
cong san » cong tac
toan cao » toan ban, toan tap
doi chi » doi khi
va dung » va duong, vat dung, va ung

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

• Performing a fuzzy search may retrieve terms with similar spellings: doi chi xanh - thanh tung ((va dung) or (van dung)) ((cong dan) OR (cong san)) toan cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doi chi xanh - thanh tung ((va dung) OR (van dung)) ((cong dan) OR (cong san)) toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chi xanh - thanh tung ((va dung) or (van dung)) ((cong dan) OR (cong san)) toan cao".
• Adding a wildcard symbol may retrieve word variants: doi chi xanh - thanh tung ((va dung) or (van dung)) ((cong dan) OR (cong san)) toan cao*.
