We have learned the details from the salesman. We have completed the production completely according to the customer's requirements, because the trailer and equipment are also confirmed by the customer in person, because we always put forward the initial plan with the highest cost performance for the customer, then communicate with the customer for details, design, add or delete, and finally determine the optimal production plan. We will be responsible for the customer's attitude, pay attention to every detail of the communication. We also believe that we will do better and better.Thanks a lot for your support
