In this Wednesday, Oct. 21, 2015 photo, a worker manufactures metal parts in an auto parts factory which a former employee said used to hide counterfeits from government inspectors in Rui'an near Wenzhou city in eastern China's Zhejiang province. Counterfeit operations are hard to crack down on since factories can easily switch between producing the local brands they are licensed to make and producing counterfeit parts by attaching foreign brand labels.
