On September 10, in front of the special vehicle exhibition area of the Chengli wrecker truck specialized factory, a crowd gathered as the vast number of Chengli's sales elites came together to participate in a special on-site practical teaching. A total of more than 40 models in four major categories were displayed on site: flatbed one-towing-two wrecker trucks, flatbed wrecker trucks with crane, integrated towing-and-lifting wrecker trucks, and separated towing-and-lifting wrecker trucks. Educating through practice, so that sales personnel truly understand the vehicles, can communicate with customers more effectively, and present the excellent special performance of our factory's wrecker trucks to customers in a detailed and convincing way.
