Abstract：
In this paper, by reducing the Post Corresponding Problem to (1) the problem of deciding whether or not the origin-constrained domino problem has periodic solutions and
(2) the problem of deciding whether or not the unrestricted domino problem has periodic solutions, it is obtained that the above two decision problems are both unsolvable.
