Field notes
The page organizes its directory around provinces and named manufacturing clusters, with province-level counts and short descriptions of local specialties. Examples include 800G modules in Suzhou, passive components in Jiashan, and optical fiber and cable in Fuyang. The homepage says searches can be narrowed by product, cluster, and district or county, but the extracted text does not reveal the listing details or contact workflow.
