Perhaps you should try some spelling variations:
chua xang » chua nang, chuc nang, chu bang
thanh bac » nhanh bac, thanh bai, thanh san
chu xanh » chu manh, chieu xanh, chuc danh
cua dung » cua dang, cua dong, qua dung
cong tac » cong ty
tac toan » tap toan, tam toan, hach toan
toan cau » 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: theo ((chu xanh) OR (chua xang)) - thanh bac ((cua dung) OR (cua cong)) cong tac toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu xanh) OR (chua xang)) - thanh bac ((cua dung) or (cua cong)) cong tac toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) OR (chua xang)) - thanh bac ((cua dung) or (cua cong)) cong tac toan cau*.
