Certification

Dear sirs and madams,

I am working in Shanghai on the airport. To get an airport pass to work airside I need a verification from my German police record. The bureau of defence in China told me that I need to go to the embassy of China in Germany to get a verification that the police record is true. It should be signed and chopped. Would you please let me know if this can be done in the embassy of China in Frankfurt. Thanks. Chris
