On June 12,2023, the customer called and wanted to know more about CAT’s excavator and quote new machines to the customer, but the customer wanted a second-hand machine, so I suggested that he could come to the CAT factory to see the second-hand machine in person, so the customer ordered a Wednesday morning High-speed rail, on the same day we received the customer, we went to CAT's factory to visit the second-hand machines and the new machines. 

The customer was satisfied with the machine and then took the customer back to the office to introduce our company and other machines that the customer wanted to know about. After talking about it, the customer said it was still to go to Jinan, I took a taxi to take the client to the high-speed rail station.
