We prove strictly that one dimension spin 1/2 Heisenberg model has a symmetry
of energy spectrum between its subspace $n$ and the subspace $L-n$ of the Fock
space. Our proof is completed by introducing two general quantum operations.
One is a flip operation of spin direction and another is a mirror reflection of
spin sites.
