At around 8 o'clock in the evening on February 22, 2020, in the cold weather of minus 25 degrees, Chengli's batch of sewage suction trucks arrived in Liaoning and was successfully delivered to the customer. Customers were full of praise for Chengli's service and proposed to purchase 10 more units next year.
No matter how difficult the conditions are, Cheng Li, as an industry leader, has the responsibility to do a good job of service. Customer satisfaction is our greatest return.
