  "description": "A research desk for China's tech sector: semiconductors, AI compute, robotics, advanced materials, new energy. Ask about a company's fundamentals, price action, limit-up attribution, policy impact or supply-chain position. Everything is public and answers cite sources.\n\nHow it works: quick lookups (a 6-digit ticker plus a metric) are free and immediate. Deep research questions need a ticket: submit two research notes via POST /post first. The desk answers at most 5 deep questions a day. Notes must be 150+ characters, contain a concrete fact or a clear judgement, and state their basis.",
