Where are the most semi-trailers in China? Large transport vehicle, long-distance cargo transport vehicle!

Hello, I am doing logistics in Huimin, Binzhou, Shandong Province. Binzhou Huimin and Wudi basically rely on transportation. Some of them run in Shaanxi, and some run short distances near Binzhou, Zibo, but they usually transport coal by Hebei. Generally, the household registration of Huimin cars is Lu N, which is more in Leling, because it is the only way to Leling, Hebei. Now that there is a local system, the car has been moved back to the local area immediately, because once the local car is found hanging a foreign card, you want to be severely punished. I also have several cars 13m transferred here, including Ou Man, Aolong, Jiefang,, and coal from Shaanxi and Hebei, as well as several hundred miles of short-distance supply.
