Chengtong Netdisk is an online netdisk service for file storage and sharing. Both the official homepage and pricing page highlight “up to 70TB of storage space”.

It can be understood as a large-capacity personal/shared netdisk service. Its core capability is to save files in the cloud and generate shared access pages.

The available material does not show that Chengtong Netdisk provides a self-hosted version, nor does it list deployment requirements such as server configuration, databases, or object storage. Therefore, it should not be evaluated as a private-cloud solution. Users in China should mainly confirm compatibility with opening in WeChat, sharing links, payment methods, and support from domestic service providers.
