Shanghai, Shenyang, Shenzhen, and Nanjing are the four main minting or printing locations for currency in China, and these sites - in some capacity - have also been used for the bullion coin production by the CGCI.

Other reports suggest sites at Wuchang, Kuailin, Lanjou, Chengdu and Qunming, as well as Taiwan. Unfortunately the Chinese government heavily protects information about the country against outside enquiries, and currency production is one of these aspects shielded, meaning accurate knowledge of the bullion minting locations isn't available at present.
