In the Kekul\\'e-ordered graphene, the original $K$ and $K^{\\prime}$ valleys of the pristine graphene are folded together due to the $\\sqrt{3} \\times \\sqrt{3}$ enlargement of the primitive cell. When the valley coupling breaks the chiral symmetry, special transport properties of Dirac electrons exist in the Kekul\\'e lattice.
