German news magazine 'Der Spiegel' is reporting about this in their online service:
Flugsicherheit: Chinesische Piloten fälschten Flugstunden-Nachweise - SPIEGEL ONLINE - Nachrichten - Wirtschaft
It says that a closer examination of their pilot's CVs has revealed that over 100 pilots of Shenzhen Airlines have forged their flying records and that pilots of other airlines are affected, too.
If you cooperate with Chinese companies, you risk that your products are being copied. If you work for them, you might not get paid. Why am I not surprised?
