I would like to ask: 1. How many tons is the annual production capacity of the project? 2. How many tons have been shipped? 3. Which country and region does the quartz sand mine come from? 4. What are the performance and quality indicators of the product? Can it meet the production requirements of the inner layer sand of the photovoltaic quartz crucible? Secretary
