The direct rail-water through transport of import and export goods from Lanzhou to Qingdao was formally put to service recently. From now on, customs declaration or clearance formalities can be performed directly at Lanzhou customs house for the city's import and export goods. One needs only to perform transit procedure in Qingdao customs house, thus putting an end to the history when goods of Gansu could not be directly put out to sea. For goods of Japan and the Republic of Korea, railway containers can directly shipped out of the sea.
