Can you please provide me with an e-mail address of the lost properties office or related persons?

I was flying out today from TAO to Seoul/ICN by OZ318. When arriving at Seoul my purse with my German ID card, my drivers licence and all my credite cards were not available. I had it last time in the Qingdao Airport duty free shop in the morning. Perhaps somebody has found the purse with all the documents.
In case you have found it please inform me and send it to me on my cost. Many thanks in advance,
