It is well known that Hall Marriage Theorem presented by Hall in 1935 is a famous and classical theory in graph theory.Inthis paper,firstly,all the graph theory concepts needed in Hall's Marriage Theorem are defined in poset theory,followed by the proof of Hall's Marriage Theorem is presented by the method of poset.Finally,a practical problem is solved by the above new way.
