Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
chua xang » chua nang, chuc nang, chu bang
cua nhung » va nhung
chu xanh » chu manh, chieu xanh, chuc danh
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: cua ((chu xanh) OR (chua xang)) - ((minh hoang) OR (canh tranh)) cua nhung cong tac toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cua ((chu xanh) OR (chua xang)) - ((minh hoang) or (canh tranh)) cua nhung cong tac toan cau~".
• Adding a wildcard symbol may retrieve word variants: cua ((chu xanh) OR (chua xang)) - ((minh hoang) or (canh tranh)) cua nhung cong tac toan cau*.
