The group company participated in the Yipaike Petrochemical Equipment Exhibition. On April 13, 2023, the company dispatched a strong technical team to participate in the Yipaike Petrochemical Equipment Exhibition. During this period, we received numerous new and old customers, had in-depth discussions with our leaders and customers, and our technical personnel provided detailed introductions to our company's product performance and production processes on site. The meeting lasted for 3 days, and the leaders of Yipaike visited the site for in-depth communication with the group leaders, reaching many cooperation intentions and pointing out the direction for the group's next planning. During this period, we also welcomed many new customers. This Yipaike Petrochemical Equipment Exhibition has pointed out the direction for the group's production in 2023. The group has made sufficient preparations to send 20 engineers to participate in the exhibition. Thank you for the strong support from both new and old customers.
