cong manh » cong danh, duong manh, cong thanh
manh toan » thanh toan, anh tuan, tinh 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 chua) OR (theo chu)) xang - ((anh tang) OR (anh bang)) va nhung cong manh toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chua) OR (theo chu)) xang - ((anh tang) or (anh bang)) va nhung cong manh toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((theo chua) OR (theo chu)) xang - ((anh tang) or (anh bang)) va nhung cong manh toan cau*.
