bang cong » dang cong, bang song, hang cong
manh toan » thanh toan, anh tuan, tinh toan

• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chau) OR (ho chu)) tinh - chinh doanh luan ((dung cong) or (bang cong)) manh toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho chau) OR (ho chu)) tinh - chinh doanh luan ((dung cong) or (bang cong)) manh toan cau*.
