When Siemens first entered China, it chose to cooperate with Wuxi Little Swan, so it was produced in Wuxi.
With the continuous expansion of production and demand, Wuxi factory has been unable to meet the requirements of production expansion.
Moreover, Siemens finally chose to sever Sino-foreign cooperation with Little Swan. Finally, they invested independently, so they chose the decision to rebuild the factory elsewhere. At present, the secondary bases are all in production, but Wuxi produces old models and high-end, and the new factory in Nanjing has started production.
