Robot Concept Stocks Rally in China; Lianhe Precision Seals Limit Up

This is a broad, synchronized move across robot-concept names rather than a single-stock story, which suggests sector-level positioning rather than company-specific news. The absence of a named catalyst in the item is itself notable: such rallies often reflect thematic flows and momentum, and can unwind as quickly as they build. The open question is whether the breadth holds — whether the smaller gainers keep pace with the limit-up leader — or whether the move narrows to a few names.
