Perhaps you should try some spelling variations:
hanh tranh » canh tranh, hanh trinh, hanh trang
tranh cua » doanh cua, manh cua
hang cong » hang nong, bang cong, thanh cong
dang cong » dung cong
manh toan » thanh toan, anh tuan, tinh toan
chu xanh » chieu xanh, chua xang, chuc danh
chu manh » ho manh, chu han, chu van
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 (chu manh)) - hanh tranh cua ((hang cong) OR (dang cong)) manh toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cua ((chu xanh) OR (chu manh)) - hanh tranh cua ((hang cong) or (dang cong)) manh toan cau~".
• Adding a wildcard symbol may retrieve word variants: cua ((chu xanh) OR (chu manh)) - hanh tranh cua ((hang cong) or (dang cong)) manh toan cau*.
