Then the correct process should be Ji 'an-Nanchang-Hangzhou-Quzhou -XXX- destination.
From the perspective of a single object, this journey is long, but in the case of less than one car from Ji 'an to Quzhou, the overall cost is the lowest for logistics companies.

In order to save the distance, it is not always necessary for people to send this project to Quzhou by car.
