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.

• Performing a fuzzy search may retrieve terms with similar spellings: chao ((chu manh) OR (chu han)) - hanh ((trinh cua) or (trinh luat)) nhung cong manh toan ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: chao ((chu manh) OR (chu han)) - hanh ((trinh cua) OR (trinh luat)) nhung cong manh toan ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "chao ((chu manh) OR (chu han)) - hanh ((trinh cua) or (trinh luat)) nhung cong manh toan ban".
• Adding a wildcard symbol may retrieve word variants: chao ((chu manh) OR (chu han)) - hanh ((trinh cua) or (trinh luat)) nhung cong manh toan ban*.
