After the Qin dynasty, the official document was divided into two types of "urgent documents" and "common documents" according to their urgency. In today's words, express delivery and postal service are used.
After the Han Dynasty, all express delivery must be delivered by the courier. Since then, the horse has become the most important means of transportation. During the period of the Southern and Northern Dynasties, emergency documents required the courier to be 200 kilometers per day. It can be seen that there is no horse that is extremely strong and able to run. It is really not ah.
"A ride on a red scorpion laughs, no one knows it is litchi." At that time, the person who gave the lychee to Yang Guixun was the express delivery service of the Tang Dynasty. The so-called "expressed by 800-plus rushes" was also a courier job.
In the Song Dynasty, there was a faster delivery method - rush delivery. The fastest hurrying hand can be "six hundred miles." In fact, the ancient unit of measure is different from that of today. The records of the "Historical Records" are about a thousand miles away, which is more than 300 kilometers. In view of the limited speed of the horses, the courier needs to change horses for each station. It seems that the horse is not It's good. If information and objects are transmitted in accordance with the rhythm of ancient times, several horses will not be exhausted. The wartime documents that the emperor wanted, and the lychee of lingnan that Chih-yin had eaten were not time-sensitive. Everything was cloudless. It seems that there is no good logistics and transportation.
Matching mature, excellent and reliable, there is no condition on the road, no delay, easily over the mountains and rivers.
Until the advent of the courier truck, it was easy to make the land transportation "on the move" become a breeze. Say express truck, had to say "Shaanxi Steam Cummins Express New Pearl", from the day it was born, it was doomed to have a red net The life, whether it is efficient or fuel-efficient, has thrown other courier vehicles several streets, the indicators easily explode!
Red heart - Cummins ISM11 litre engine, fast, quick start, high efficiency, save time, B10 design life is up to 2 million kilometers, reliable and proper, parcels do not wait. Fast direct transmission gearbox + Handel small speed ratio, match mature, excellent and reliable, no condition on the road, no delay, easily over the mountains and rivers.
Cummins ISM 11-liter engine, fast, quick start, high efficiency, save time
This "good horse" is not only highly efficient, but "grass" also eat less. The Celect electronically controlled fuel system unique to the Cummins ISM 11 engine has high injection pressure, good atomization, and more fuel economy. In addition, Tian Xingjian's "Zhi Xing Edition" service system controls real fuel consumption and corrects bad driving habits so that the express fleet fuel cost can save 5%-10% annually.
