Perhaps you should try some spelling variations:
manh hung » anh huong
chi xanh » chi anh, chi hanh, chieu xanh
chi danh » chi dan, chi anh, chi dinh
ung cong » dung cong, luong cong, duong cong
cong tan » cong tac, cong san, cong thanh
tan toan » tan tran, tap toan, van toan
toan cao » toan ban, toan tap

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

• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chi xanh) OR (chi danh)) - ((sinh trung) OR (manh hung)) dap ung cong tan toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chi xanh) OR (chi danh)) - ((sinh trung) or (manh hung)) dap ung cong tan toan cao~".
• Adding a wildcard symbol may retrieve word variants: doi ((chi xanh) OR (chi danh)) - ((sinh trung) or (manh hung)) dap ung cong tan toan cao*.
