Guatemala old customers, the customers are mainly compressor filters, and we have been cooperating with customers in 2015 until now, and the clients are Atlas copco agents. Although customers have strict requirements on product quality and packaging, our products meet customer requirements, and customers recognize our products. This customer purchases products in bulk, three times a year, once at the beginning of the year, once in the middle of the year, and once at the end of the year. Because the distance is relatively long, customers are all shipped by sea. The customers are customer groups such as service food factories and air compressor after-sales. It's very compatible with us. Customers are very satisfied with our service. We are not only good partners at work, but also good friends in life. We not only send holiday wishes to customers, but also give different gifts to our customers. We hope that our relationship will get better and better.
