Which companies in Hangzhou are operated by Amazon?

Let's talk about the famous Mike technology in Hangzhou first, so I won't mention the messy small companies. This company is actually not only operated by Amazon, but also a company integrating cross-border e-commerce consulting services, Amazon operation training services and international promotion services. There are many cross-border e-commerce related services. Amazon's operation is their main project, and it has been doing well in Hangzhou, and the user feedback is also good.
