Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
huong cua » dung cua
chua xang » chua nang, chuc nang, chu bang
cua nhung » va nhung
manh toan » thanh toan, anh tuan, tinh toan
chu xanh » chu manh, chieu xanh, chuc danh
dan toan » van toan, dan than, xuan toan

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)) - anh huong cua nhung cong ((dan toan) OR (manh toan)) cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu xanh) OR (chua xang)) - anh huong cua nhung cong ((dan toan) or (manh toan)) cao~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) OR (chua xang)) - anh huong cua nhung cong ((dan toan) or (manh toan)) cao*.
