What should I do if the number cloth of Qingdao Marathon is lost?

Can't get the competition results. The chips of Qingdao Marathon are basically disposable chips, which are placed in numbered cloth. If you don't pick up the numbered cloth and reuse it, you won't get the competition results. Qingdao, also known as Island City, Qingdao and Jiaoao, is a prefecture-level city, a sub-provincial city, a city with separate plans and a megacity under the jurisdiction of Shandong Province, China. Located in the south of Shandong Peninsula.
