xuan hung » xuan huong, xuan chung, luan hung
hung cong » nhung cong, hung cuong, phung cong
manh toan » thanh toan, tinh toan

• If you are trying to use Boolean operators, they must be ALL CAPS: chon chinh sach - thanh hoa xuan hung cong ((san toan) OR (((manh toan) OR (anh tuan)))) tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "chon chinh sach - thanh hoa xuan hung cong ((san toan) or (((manh toan) OR (anh tuan)))) tap~".
• Adding a wildcard symbol may retrieve word variants: chon chinh sach - thanh hoa xuan hung cong ((san toan) or (((manh toan) OR (anh tuan)))) tap*.
