The Industrial Map of Chinese Manufacturing
We publish structural research industry by industry, at the granularity of individual industrial clusters, built on real factory samples. Every report cross-references two sources — public membership rolls from trade associations, and verified factories identified by Tianxia Gongchang. The full factory list lives on the main platform.
4.8 Million Real Factories × AI: The Data Foundation Race in Supply Chain Discovery
Enterprise information coverage does not equal factory coverage; product catalog coverage does not equal production capacity coverage. In the new AI-driven phase of supply chain discovery, the quality of the data foundation — not its scale — is becoming the decisive variable that determines an AI system's capability ceiling.

Cracking the 'Unfiltered Dimension' Problem: How AI-Verified Recall Fills Structured Data Gaps
Export qualifications, niche certifications, and specialized processes cannot be pre-indexed as structured fields. Traditional search either ignores these dimensions or returns spuriously precise large recall sets. AI online verification combined with in-database cross-checking is closing the structured data gaps in supply chain discovery.

AI Is Reshaping B2B Factory Discovery: From Keyword Search to Conversational Finding
The structural limitations of keyword search are constraining B2B factory sourcing efficiency. Conversational AI — through iterative requirement clarification and real-data counter-questioning — is redefining the factory discovery paradigm.
