In December 2019, our regular customer rushed to purchase a batch of stainless steel pipes to decorate a shopping mall. Because December is the peak season, the delivery period is relatively long. But the customer is eager to deliver the goods within 15 days. Because our production plan has been arranged, if we want to deliver the goods within 15 days and ensure the quality, we must adjust the production plan and arrange for workers to work overtime to complete it. In order to meet the needs of customers, we finally completed the order on time under the premise of ensuring quality. The customer finally completed his project on time. Since then, we have been happily cooperating with this customer until now.
