URL in description and README broken

The URL in the repository description and the one in the README are pointing to githubschool's copy of the game instead of yours.

Please fix both so they point to your copy of the game at https://githubschool.github.io/github-games-XueqingDingDing

Open the README and inspect the repository description settings. Replace both existing links with https://githubschool.github.io/github-games-XueqingDingDing, then verify that the README link and repository description point to the requested copy of the game.
