The Company continuously monitors market trends across its business units to formulate forward-looking product development strategies while establishing diverse customer communication channels. These channels include regular meetings, an official website, a customer service hotline, and an email system to ensure timely and effective information sharing. To address customer concerns regarding production, quality, delivery, and SER (Social and Environmental Responsibility), the Company implements the "137 System" for a prompt response.
To enhance customer relationship management, we require our sales department to schedule regular monthly or weekly meetings with customers. These meetings serve not only to review existing collaborations but also to present and promote our latest R&D achievements, ensuring advance integration of necessary resources for future project success.
