The starting point is Yiwu and the end point is Yinchuan, Ningxia. How to choose the fastest, most convenient and most economical way to travel by train and plane?

There is a through train from Yinchuan to Yiwu. If safety and convenience are considered more, the plane is still a good choice.

I remember all flights from Yinchuan to Pudong, so I think it is more reliable to fly to Xi 'an for a connecting flight. There are many cheap flights from Xi 'an to Yinchuan. It seems that there are flights from 7 am to 7 pm 10 every day. The lowest discount plus capital construction fuel is more cost-effective.
