cong manh » cong danh, duong manh, cong thanh
manh toan » thanh toan, anh tuan, tinh toan
chu manh » ho manh, chu han, chu van
tang van » dang van, hoang van, trong van
toan cau » toan cao, toan ban, toan tap
tang va » trang va, thang va, tang vat

You may be able to get more results by adjusting your search query.

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